98-496: The following is a list of Microsoft Windows components . This list is not all-inclusive. Microsoft Windows 24H2 (10.0.26100.2454) (November 21, 2024 ; 7 days ago ( 2024-11-21 ) ) [±] 23H2 (10.0.22635.4515) (November 22, 2024 ; 6 days ago ( 2024-11-22 ) ) [±] 24H2 (10.0.26120.2415) (November 22, 2024 ; 6 days ago ( 2024-11-22 ) ) [±] Microsoft Windows
196-452: A graphical user interface (GUI) to be sold commercially. It uses a Motorola 68000 CPU clocked at 5 MHz and has 1 MB of RAM. It can be upgraded to 2 MB and later shipped with as little as 512 kilobytes. The CPU speed and model were not changed from the release of the Lisa 1 to the repackaging of the hardware as Macintosh XL. The real-time clock uses a 4-bit integer and the base year
294-729: A web browser . The new service is an attempt at capitalizing on the growing trend, fostered during the COVID-19 pandemic , for businesses to adopt a hybrid remote work environment, in which "employees split their time between the office and home". As the service will be accessible through web browsers, Microsoft will be able to bypass the need to publish the service through Google Play or the Apple App Store . Microsoft announced Windows 365 availability to business and enterprise customers on August 2, 2021. Multilingual support has been built into Windows since Windows 3.0. The language for both
392-623: A 12-inch (30 cm) screen. Lisa's printer support includes Apple's Dot Matrix , Daisy Wheel , and ImageWriter dot matrix printers, and Canon 's new color inkjet technology. The original Lisa, later called the Lisa 1, has two FileWare 5.25-inch double-sided variable-speed floppy disk drives, more commonly known by Apple's codename "Twiggy". They have what was then a very high capacity of approximately 871 kB each, but are unreliable and use proprietary diskettes. Competing systems with high diskette data storage have much larger 8" floppy disks, seen as cumbersome and old-fashioned for
490-550: A change which Microsoft promised would provide better performance over its DOS-based predecessors. Windows XP would also introduce a redesigned user interface (including an updated Start menu and a "task-oriented" Windows Explorer ), streamlined multimedia and networking features, Internet Explorer 6 , integration with Microsoft's .NET Passport services, a " compatibility mode " to help provide backwards compatibility with software designed for previous versions of Windows, and Remote Assistance functionality. At retail, Windows XP
588-464: A consumer system. Lisa 1's innovations include block sparing, to reserve blocks in case of bad blocks, even on floppy disks. Critical operating system information has redundant storage, for recovery in case of corruption. The first hardware revision, the Lisa 2, was released in January 1984 and was priced between $ 3,495 and $ 5,495 . It was much less expensive than the original model, and dropped
686-508: A large number of new features, Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware with which Windows Vista was already compatible. Windows 7 has multi-touch support, a redesigned Windows shell with an updated taskbar with revealable jump lists that contain shortcuts to files frequently used with specific applications and shortcuts to tasks within
784-409: A larger, higher-resolution display. Lisa's CPU and the storage system were strained by the complexity of the operating system and applications, especially its office suite , and by the ad hoc protected memory implementation, due to the lack of a Motorola memory management unit . Cost-cutting measures that target the consumer market, and the delayed availability of the 68000 processor and its impact on
882-598: A machine like the Lisa was still so expensive that it was primarily marketed to individual and small and medium-sized businesses as a groundbreaking new alternative to much bigger and more expensive mainframes or minicomputers such as from IBM , that either require additional, expensive consultancy from the supplier, hiring specially trained personnel, or at least, a much steeper learning curve to maintain and operate. Earlier GUI-controlled personal computers were not mass-marketed; for example, Xerox PARC manufactured its Alto workstation only for Xerox and select partners from
980-486: A marketing consultancy firm to find names to replace "Lisa" and "Macintosh" (at the time considered by Jef Raskin to be merely internal project codenames) and then rejected all of the suggestions. Privately, Hertzfeld and the other software developers used "Lisa: Invented Stupid Acronym", a recursive backronym , and computer industry pundits coined the term "Let's Invent Some Acronym" to fit Lisa's name. Decades later, Jobs told his biographer Walter Isaacson : "Obviously it
1078-595: A modular, portable kernel with preemptive multitasking and support for multiple processor architectures. However, following the successful release of Windows 3.0 , the NT development team decided to rework the project to use an extended 32-bit port of the Windows API known as Win32 instead of those of OS/2. Win32 maintained a similar structure to the Windows APIs (allowing existing Windows applications to easily be ported to

#17328527271731176-400: A new Windows 365 service in the following month. The new service will allow for cross-platform usage , aiming to make the operating system available for both Apple and Android users. It is a separate service and offers several variations including Windows 365 Frontline, Windows 365 Boot, and the Windows 365 app. The subscription service will be accessible through any operating system with
1274-563: A program called "Interface Manager". The name "Windows" comes from the fact that the system was one of the first to use graphical boxes to represent programs; in the industry, at the time, these were called "windows" and the underlying software was called "windowing software." It was announced in November 1983 (after the Apple Lisa , but before the Macintosh ) under the name "Windows", but Windows 1.0
1372-506: A redesigned, object oriented user interface, replacing the previous Program Manager with the Start menu , taskbar , and Windows Explorer shell . Windows 95 was a major commercial success for Microsoft; Ina Fried of CNET remarked that "by the time Windows 95 was finally ushered off the market in 2001, it had become a fixture on computer desktops around the world." Microsoft published four OEM Service Releases (OSR) of Windows 95, each of which
1470-460: A special version with integrated peer-to-peer networking features and a version number of 3.11, was released. It was sold along with Windows 3.1. Support for Windows 3.1 ended on December 31, 2001. Windows 3.2, released in 1994, is an updated version of the Chinese version of Windows 3.1. The update was limited to this language version, as it fixed only issues related to the complex writing system of
1568-529: A specific base language and are commonly used for more popular languages such as French or Chinese. These languages cannot be downloaded through the Download Center, but are available as optional updates through the Windows Update service (except Windows 8). The interface language of installed applications is not affected by changes in the Windows interface language. The availability of languages depends on
1666-416: A successor to NT 4.0. The Windows NT name was dropped at this point in order to put a greater focus on the Windows brand. The next major version of Windows NT, Windows XP , was released to manufacturing (RTM) on August 24, 2001, and to the general public on October 25, 2001. The introduction of Windows XP aimed to unify the consumer-oriented Windows 9x series with the architecture introduced by Windows NT,
1764-454: A text-based appliance computer. Jobs redefined Macintosh as a cheaper and more usable form of Lisa's concepts, and led the skunkworks project with substantial motivation to compete in parallel with the Lisa team. In September 1981, below the announcement of the IBM PC , InfoWorld reported on Lisa, "McIntosh", and another Apple computer secretly under development "to be ready for release within
1862-454: A year". It described Lisa as having a 68000 processor and 128KB RAM, and "designed to compete with the new Xerox Star at a considerably lower price". In May 1982, the magazine reported that "Apple's yet-to-be-announced Lisa 68000 network work station is also widely rumored to have a mouse ." Apple Confidential said, "Finally, and perhaps most damaging, even before the Lisa began shipping in June,
1960-549: Is a product line of proprietary graphical operating systems developed and marketed by Microsoft . It is grouped into families and sub-families that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation , Windows Server for a server and Windows IoT for an embedded system . Windows is sold as either a consumer retail product or licensed to third-party hardware manufacturers who sell products bundled with Windows. The first version of Windows, Windows 1.0 ,
2058-435: Is an edition of Windows that runs on minimalistic computers , like satellite navigation systems and some mobile phones. Windows Embedded Compact is based on its own dedicated kernel, dubbed Windows CE kernel. Microsoft licenses Windows CE to OEMs and device makers. The OEMs and device makers can modify and create their own user interfaces and experiences, while Windows CE provides the technical foundation to do so. Windows CE

#17328527271732156-450: Is an unofficial name given to the version of Windows that runs on Xbox consoles. From Xbox One onwards it is an implementation with an emphasis on virtualization (using Hyper-V ) as it is three operating systems running at once, consisting of the core operating system , a second implemented for games and a more Windows-like environment for applications. Microsoft updates Xbox One's OS every month, and these updates can be downloaded from
2254-539: Is available under an Apple Academic License Agreement. In April 1984, following the Macintosh launch, Apple introduced MacWorks, a software emulation environment enabling Lisa to run Macintosh System software and applications. MacWorks improved Lisa's market appeal. After the early Macintosh operating system first gained hard disk support, MacWorks also gained access to Lisa's hard disk in September. In January 1985, MacWorks
2352-485: Is defined as 1980; the software won't accept any value below 1981, so the only valid range is 1981–1995. The real-time clock depends on a 4 × AA-cell NiCd pack of batteries that only lasts for a few hours when main power is not present. Prone to failure over time, the battery packs could leak corrosive alkaline electrolyte and ruin the circuit boards. The integrated monochrome black-on-white monitor has 720 × 364 rectangular pixels on
2450-523: Is said to be available to update from qualified Windows 7 with SP1, Windows 8.1 and Windows Phone 8.1 devices from the Get Windows 10 Application (for Windows 7 , Windows 8.1 ) or Windows Update ( Windows 7 ). In February 2017, Microsoft announced the migration of its Windows source code repository from Perforce to Git . This migration involved 3.5 million separate files in a 300-gigabyte repository. By May 2017, 90 percent of its engineering team
2548-573: Is the most popular desktop operating system in the world, with a 70% market share as of March 2023 , according to StatCounter ; however when including mobile OS es, it is not the most used, in favor of Android . As of today, the most recent version of Windows is Windows 11 for consumer PCs and tablets , Windows 11 Enterprise for corporations, and Windows Server 2025 for servers. Still supported are some editions of Windows 10 , Windows Server 2016 or later (and exceptionally with paid support down to Windows Server 2008 ). As of today,
2646-447: Is the last Windows client operating system to support Itanium. Windows Server line continues to support this platform until Windows Server 2012 ; Windows Server 2008 R2 is the last Windows operating system to support Itanium architecture. On April 25, 2005, Microsoft released Windows XP Professional x64 Edition and Windows Server 2003 x64 editions to support x86-64 (or simply x64), the 64-bit version of x86 architecture. Windows Vista
2744-457: The Apple II division upon taking Raskin's project. Newer Lisa models addressed its shortcomings but, even with a major price reduction, the platform failed to achieve sales volumes comparable to the much less expensive Mac. The Lisa 2/10 is the final model, then rebranded as the high-end Macintosh XL . Though the original documentation only refers to it as "The Lisa", Apple officially stated that
2842-520: The Apple III SOS operating system released three years earlier, Lisa's disk operating system also organizes its files in hierarchical directories. File system directories correspond to GUI folders, as with previous Xerox PARC computers from which Lisa borrowed heavily. Lisa was designed around a hard drive, unlike the first Macintosh. Lisa has two main user modes: the Lisa Office System and
2940-474: The Apple III of 1980. Apple sold a total of approximately 10,000 Lisa machines at US$ 9,995 (equivalent to about $ 30,600 in 2023) each, generating total sales of $ 100 million against a development cost of more than $ 150 million . The largest Lisa customer was NASA , which used LisaProject for project management. The Lisa 2 and its Mac ROM -enabled Macintosh XL version are the final two releases in
3038-578: The Macintosh Plus was introduced in 1986. The Lisa operating system features protected memory , enabled by a crude hardware circuit compared to the Sun-1 workstation (c. 1982), which features a full memory management unit. Motorola did not have an MMU (memory-management unit) for the 68000 ready in time, so third parties developed their own. Apple's is also the result of a cost-cutting compromise, with sluggish performance. Based, in part, on elements from

3136-585: The Start screen , which uses large tiles that are more convenient for touch interactions and allow for the display of continually updated information, and a new class of apps which are designed primarily for use on touch-based devices. The new Windows version required a minimum resolution of 1024×768 pixels, effectively making it unfit for netbooks with 800×600-pixel screens. Other changes include increased integration with cloud services and other online platforms (such as social networks and Microsoft's own OneDrive (formerly SkyDrive) and Xbox Live services),
3234-950: The Windows Driver Model , support for USB composite devices , support for ACPI , hibernation , and support for multi-monitor configurations. Windows 98 also included integration with Internet Explorer 4 through Active Desktop and other aspects of the Windows Desktop Update (a series of enhancements to the Explorer shell which was also made available for Windows 95). In May 1999, Microsoft released Windows 98 Second Edition , an updated version of Windows 98. Windows 98 SE added Internet Explorer 5.0 and Windows Media Player 6.2 amongst other upgrades. Mainstream support for Windows 98 ended on June 30, 2002, and extended support for Windows 98 ended on July 11, 2006. On September 14, 2000, Microsoft released Windows Me (Millennium Edition),
3332-494: The Windows Image Acquisition framework for retrieving images from scanners and digital cameras), additional system utilities such as System File Protection and System Restore , and updated home networking tools. However, Windows Me was faced with criticism for its speed and instability, along with hardware compatibility issues and its removal of real mode DOS support. PC World considered Windows Me to be one of
3430-568: The Windows Store service for software distribution, and a new variant known as Windows RT for use on devices that utilize the ARM architecture , and a new keyboard shortcut for screenshots . An update to Windows 8, called Windows 8.1 , was released on October 17, 2013, and includes features such as new live tile sizes, deeper OneDrive integration, and many other revisions. Windows 8 and Windows 8.1 have been subject to some criticism, such as
3528-546: The desktop metaphor . Steve Jobs visited PARC in 1979 and was absorbed and excited by the revolutionary mouse-driven GUI of the Alto . By late 1979, Jobs successfully negotiated a sale of Apple stock to Xerox, in exchange for his Lisa team receiving two demonstrations of ongoing research projects at PARC. When the Apple team saw the demonstration of the Alto computer, they were able to see in action
3626-448: The x86 -based personal computer became dominant in the professional world. Windows NT 4.0 and its predecessors supported PowerPC , DEC Alpha and MIPS R4000 (although some of the platforms implement 64-bit computing , the OS treated them as 32-bit). Windows 2000 dropped support for all platforms, except the third generation x86 (known as IA-32 ) or newer in 32-bit mode. The client line of
3724-446: The "Tablet PC" edition (designed for mobile devices meeting its specifications for a tablet computer , with support for stylus pen input and additional pen-enabled applications). Mainstream support for Windows XP ended on April 14, 2009. Extended support ended on April 8, 2014. After Windows 2000, Microsoft also changed its release schedules for server operating systems; the server counterpart of Windows XP, Windows Server 2003 ,
3822-726: The C development environment, which included numerous windows samples. Windows 2.0 was released in December 1987, and was more popular than its predecessor. It features several improvements to the user interface and memory management. Windows 2.03 changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit against Microsoft alleging infringement on Apple's copyrights (eventually settled in court in Microsoft's favor in 1993). Windows 2.0 also introduced more sophisticated keyboard shortcuts and could make use of expanded memory . Windows 2.1
3920-589: The Chinese language. Windows 3.2 was generally sold by computer manufacturers with a ten-disk version of MS-DOS that also had Simplified Chinese characters in basic output and some translated utilities. The next major consumer-oriented release of Windows, Windows 95 , was released on August 24, 1995. While still remaining MS-DOS-based, Windows 95 introduced support for native 32-bit applications , plug and play hardware, preemptive multitasking , long file names of up to 255 characters, and provided increased stability over its predecessors. Windows 95 also introduced
4018-471: The Lisa and wrote in February 1983 that it was "the most important development in computers in the last five years, easily outpacing [the IBM PC ]". It acknowledged that the $ 9,995 price was high, and concluded "Apple ... is not unaware that most people would be incredibly interested in a similar but less expensive machine. We'll see what happens". The Lisa was a commercial failure, the company's largest since

4116-430: The Lisa had been hard work. He said the system's hard disk and RAM was a requirement and not a luxury, but that the system remains slow. He noted that, by 1989, Lisa's level of integration between applications had not yet been repeated by Apple. Original "Twiggy" based Lisa 1 systems command high prices at auction due to the scarcity of surviving examples. The auction record for a Lisa 1 was set on September 10, 2024, when
4214-613: The Lisa line, which was discontinued in April 1985. The Macintosh XL is a hardware and software conversion kit to effectively reboot Lisa into Macintosh mode. In 1986, Apple offered all Lisa and XL owners the opportunity to return their computer and pay $ 1,498 , in exchange for a Macintosh Plus and Hard Disk 20 . Reportedly, 2,700 working but unsold Lisa computers were buried in a landfill. The Macintosh project, led by Steve Jobs, borrowed heavily from Lisa's GUI paradigm and directly took many of its staff, to create Apple's flagship platform of
4312-465: The Lisa only had the original seven applications that Apple had deemed enough to "do everything". UniPress Software released UNIX System III for $ 495 (equivalent to $ 1,500 in 2023). Santa Cruz Operation (SCO) published Microsoft Xenix (version 3), a Unix-like command-line operating system for the Lisa 2, and Microsoft's Multiplan 2.1 spreadsheet for Xenix. Other Lisa Xenix apps include Quadratron's Q-Office suite. BYTE previewed
4410-492: The Lisa, as compared to the earlier Apple II — AST offered a 1.5 MB memory board which, when combined with the standard Apple 512 KB memory board, expanded the Lisa to a total of 2 MB of memory, the maximum amount that the MMU can address. Late in the product life of the Lisa, there were third-party hard disk drives, SCSI controllers , and double-sided 3.5-inch floppy-disk upgrades. Unlike
4508-430: The Macintosh project from Jef Raskin , who had conceived it as a sub- $ 1,000 (equivalent to $ 4,200 in 2023) text-based appliance computer in 1979. Jobs immediately redefined Macintosh to be graphical, but as a less expensive and more focused alternative to Lisa. Macintosh's launch in January 1984 quickly surpassed Lisa's underwhelming sales. Jobs began assimilating increasing numbers of Lisa staff, as he had done with
4606-470: The Twiggy floppy drives in favor of a single 400K Sony microfloppy . The Lisa 2 has as little as 512 KB of RAM. The Lisa 2/5 consists of a Lisa 2 bundled with an external 5- or 10-megabyte hard drive. In 1984, at the same time the Macintosh was officially announced, Apple offered free upgrades to the Lisa 2/5 to all Lisa 1 owners, by replacing the pair of Twiggy drives with a single 3.5-inch drive, and updating
4704-575: The Windows NT family still ran on IA-32 up to Windows 10 (the server line of the Windows NT family still ran on IA-32 up to Windows Server 2008 ). With the introduction of the Intel Itanium architecture ( IA-64 ), Microsoft released new versions of Windows to support it. Itanium versions of Windows XP and Windows Server 2003 were released at the same time as their mainstream x86 counterparts. Windows XP 64-Bit Edition (Version 2003), released in 2003,

Full Language Packs, which translate the complete operating system, are only available for specific editions of Windows (Ultimate and Enterprise editions of Windows Vista and 7, and all editions of Windows 8, 8.1 and RT except Single Language). They do not require
4900-699: The Workshop. The Lisa Office System is the GUI environment for end users. The Workshop is a program development environment and is almost entirely text-based, though it uses a GUI text editor. The Lisa Office System was eventually renamed 7/7 which refers to the seven supplied application programs: LisaWrite, LisaCalc, LisaDraw, LisaGraph, LisaProject , LisaList, and LisaTerminal. Apple's warranty said that this software works precisely as stated, and Apple refunded an unspecified number of users, in full, for their systems. These operating system frailties, and costly recalls, combined with
4998-616: The Xbox 360's system is backwards compatible with the original Xbox. Up to and including every version before Windows 2000 , Microsoft used an in-house version control system named Source Library Manager (SLM). Shortly after Windows 2000 was released, Microsoft switched to a fork of Perforce named Source Depot. This system was used up until 2017 once the system could not keep up with the size of Windows. Microsoft had begun to integrate Git into Team Foundation Server in 2013, but Windows (and Office) continued to rely on Source Depot. The Windows code

It was originally based on NT 6.2 (Windows 8) kernel, and the latest version runs on an NT 10.0 base. This system is sometimes referred to as "Windows 10 on Xbox One". Xbox One and Xbox Series operating systems also allow limited (due to licensing restrictions and testing resources) backward compatibility with previous generation hardware, and
5194-452: The application developers themselves. Windows 8 and Windows Server 2012 introduce a new Language Control Panel where both the interface and input languages can be simultaneously changed, and language packs, regardless of type, can be downloaded from a central location. The PC Settings app in Windows 8.1 and Windows Server 2012 R2 also includes a counterpart settings page for this. Changing
5292-437: The application, a home networking system called HomeGroup , and performance improvements. Windows 8 , the successor to Windows 7, was released generally on October 26, 2012. A number of significant changes were made on Windows 8, including the introduction of a user interface based around Microsoft's Metro design language with optimizations for touch-based devices such as tablets and all-in-one PCs. These changes include
5390-440: The basic elements of what constituted a workable GUI. The Lisa team put a great deal of work into making the graphical interface a mainstream commercial product. The Lisa was a major project at Apple, which reportedly spent more than $ 50 million on its development. More than 90 people participated in the design, plus more in the sales and marketing effort, to launch the machine. BYTE magazine credited Wayne Rosing with being
5488-461: The boot ROM and I/O ROM. In addition, the Lisa 2's new front faceplate accommodates the reconfigured floppy disk drive, and it includes the new inlaid Apple logo and the first Snow White design language elements. The Lisa 2/10 has a 10 MB internal hard drive, no parallel port, and a standard configuration of 1 MB of RAM. Developing early Macintosh software required a Lisa 2. There were relatively few third-party hardware offerings for
5586-432: The design process, made the user experience sluggish. The workstation -tier high price and lack of a technical software application library made it a difficult sale for all markets. The IBM PC's popularity and Apple's decision to compete with itself through the lower-priced Macintosh also hindered Lisa's acceptance. In 1982, after Steve Jobs was forced out of the Lisa project by Apple's board of directors, he appropriated

Windows 3.0 applications can run in protected mode , which gives them access to several megabytes of memory without the obligation to participate in the software virtual memory scheme. They run inside the same address space, where
5782-432: The early to mid-1970s. Development of project "LISA" began in 1978. It underwent many changes and shipped at US$ 9,995 (equivalent to $ 30,600 in 2023) with a five-megabyte hard drive . It was affected by its high price, insufficient software, unreliable FileWare ( codename Twiggy) floppy disks , and the imminent release of the cheaper and faster Macintosh . Only 60,000 Lisa units were sold in two years. Lisa
5880-465: The firm that eventually became IDEO. Bruce Daniels was in charge of applications development, and Larry Tesler was in charge of system software. The user interface was designed in six months, after which the hardware, operating system, and applications were all created in parallel. In 1982, Steve Jobs was forced out of the Lisa project, and he appropriated Jef Raskin 's existing Macintosh project. Raskin had conceived and led Macintosh since 1979 as
5978-516: The full Windows feature set. The early versions of Windows are often thought of as graphical shells, mostly because they ran on top of MS-DOS and used it for file system services. However, even the earliest Windows versions already assumed many typical operating system functions; notably, having their own executable file format and providing their own device drivers (timer, graphics, printer, mouse, keyboard and sound). Unlike MS-DOS, Windows allowed users to execute multiple graphical applications at

#17328527271736076-468: The help of Sun Remarketing, Apple disposed of approximately 2,700 unsold Lisa units in a guarded landfill in Logan, Utah , to receive a tax write-off on the unsold inventory. Some leftover Lisa computers and spare parts were available until Cherokee Data (which purchased Sun Remarketing) went out of business. The Lisa was first introduced on January 19, 1983. It is one of the first personal computer systems with
6174-436: The interface language also changes the language of preinstalled Windows Store apps (such as Mail, Maps and News) and certain other Microsoft-developed apps (such as Remote Desktop). The above limitations for language packs are however still in effect, except that full language packs can be installed for any edition except Single Language, which caters to emerging markets. Windows NT included support for several platforms before
6272-505: The keyboard and the interface can be changed through the Region and Language Control Panel. Components for all supported input languages, such as Input Method Editors , are automatically installed during Windows installation (in Windows XP and earlier, files for East Asian languages, such as Chinese, and files for right-to-left scripts, such as Arabic, may need to be installed separately, also from
6370-433: The last DOS-based version of Windows. Windows Me incorporated visual interface enhancements from its Windows NT-based counterpart Windows 2000 , had faster boot times than previous versions (which however, required the removal of the ability to access a real mode DOS environment, removing compatibility with some older programs), expanded multimedia functionality (including Windows Media Player 7, Windows Movie Maker , and
6468-532: The most important person in the development of the computer's hardware until the machine went into production, at which point he became the technical lead for the entire Lisa project. The hardware development team was headed by Robert Paratore. The industrial design, product design, and mechanical packaging were headed by Bill Dresselhaus, the Principal Product Designer of Lisa, with his team of internal product designers and contract product designers from
6566-530: The much less expensive Mac. The Macintosh project assimilated a lot more Lisa staff. The final revision, the Lisa 2/10, was modified and sold as the Macintosh XL . The high cost and the delays in its release date contributed to the Lisa's discontinuation although it was repackaged and sold at $ 4,995 , as the Lisa 2. In 1986, the entire Lisa platform was discontinued. In 1987, Sun Remarketing purchased about 5,000 Macintosh XLs and upgraded them. In 1989, with
6664-441: The name was an acronym for "Local Integrated Software Architecture". Because Steve Jobs's first daughter was named Lisa (born in 1978), it was sometimes inferred that the name also had a personal association, and perhaps that the acronym was a backronym contrived later to fit the name. Andy Hertzfeld said that the acronym was reverse-engineered from the name "Lisa" in late 1982 by the Apple marketing team after they had hired
6762-477: The next several decades. The column-based interface , for instance, utilized by Mac OS X, had originally been developed for Lisa. It had been discarded in favor of the icon view. Apple's culture of object-oriented programming on Lisa contributed to the 1988 conception of Pink , the first attempt to re-architect the operating system of Macintosh. In 1989, after Wayne Rosing had moved to Sun Microsystems , he reflected on his time at Apple, recalling that building
6860-622: The only active top-level family is Windows NT . The first version, Windows NT 3.1 , was intended for server computing and corporate workstations . It grew into a product line of its own and now consists of four sub-families that tend to be released almost simultaneously and share the same kernel. These top-level Windows families are no longer actively developed: The term Windows collectively describes any or all of several generations of Microsoft operating system products. These products are generally categorized as follows: The history of Windows dates back to 1981 when Microsoft started work on
6958-429: The original Macintosh, the Lisa has expansion slots. The Lisa 2 motherboard has a very basic backplane with virtually no electronic components, but plenty of edge connector sockets and slots. There are two RAM slots, one CPU upgrade slot, and one I/O slot, all in parallel. At the other end are three Lisa slots in parallel. In January 1985, following the Macintosh, the Lisa 2/10 (with integrated 10 MB hard drive)
7056-403: The platform), but also supported the capabilities of the existing NT kernel . Following its approval by Microsoft's staff, development continued on what was now Windows NT, the first 32-bit version of Windows. However, IBM objected to the changes, and ultimately continued OS/2 development on its own. Windows NT was the first Windows operating system based on a hybrid kernel . The hybrid kernel
7154-448: The press was full of intentionally-leaked rumors about a fall release of a 'baby Lisa' that would work in much the same way, only faster and cheaper. Its name: Macintosh." Lisa was launched on January 19, 1983. Its low sales were quickly surpassed by the January 1984 launch of the Macintosh. Newer versions of the Lisa were introduced that addressed its faults and lowered its price considerably, but it failed to achieve sales comparable to
7252-401: The project evolved into the " window-and-mouse-driven " form of its eventual release. Trip Hawkins and Jef Raskin contributed to this change in design. Apple's co-founder Steve Jobs was involved in the concept. At Xerox's Palo Alto Research Center (PARC), research had already been underway for several years to create a new humanized way to organize the computer screen, which became known as
7350-489: The removal of the Start menu . On September 30, 2014, Microsoft announced Windows 10 as the successor to Windows 8.1. It was released on July 29, 2015, and addresses shortcomings in the user interface first introduced with Windows 8. Changes on PC include the return of the Start Menu, a virtual desktop system, and the ability to run Windows Store apps within windows on the desktop rather than in full-screen mode. Windows 10
7448-751: The said Control Panel). Third-party IMEs may also be installed if a user feels that the provided one is insufficient for their needs. Since Windows 2000, English editions of Windows NT have East Asian IMEs (such as Microsoft Pinyin IME and Microsoft Japanese IME) bundled, but files for East Asian languages may be manually installed on Control Panel. Interface languages for the operating system are free for download, but some languages are limited to certain editions of Windows. Language Interface Packs (LIPs) are redistributable and may be downloaded from Microsoft's Download Center and installed for any edition of Windows (XP or later) – they translate most, but not all, of
7546-420: The same time, through cooperative multitasking . Windows implemented an elaborate, segment-based, software virtual memory scheme, which allows it to run applications larger than available memory: code segments and resources are swapped in and thrown away when memory became scarce; data segments moved in memory when a given application had relinquished processor control. Windows 3.0 , released in 1990, improved
7644-439: The segmented memory provides a degree of protection. Windows 3.0 also featured improvements to the user interface. Microsoft rewrote critical operations from C into assembly . Windows 3.0 was the first version of Windows to achieve broad commercial success, selling 2 million copies in the first six months. Windows 3.1, made generally available on March 1, 1992, featured a facelift. In August 1993, Windows for Workgroups,
7742-691: The very high price point, led to the failure of the Lisa in the marketplace. NASA purchased Lisa machines, mainly to use the LisaProject program. In 2018, the Computer History Museum announced it would be releasing the source code for Lisa OS, following a check by Apple to ensure this would not impact other intellectual property. For copyright reasons, this release does not include the American Heritage dictionary. For its 40th anniversary on January 19, 2023, Lisa OS Software version 3.1's source code
7840-465: The worst operating systems Microsoft had ever released, and the fourth worst tech product of all time. In November 1988, a new development team within Microsoft (which included former Digital Equipment Corporation developers Dave Cutler and Mark Lucovsky ) began work on a revamped version of IBM and Microsoft's OS/2 operating system known as "NT OS/2". NT OS/2 was intended to be a secure, multi-user operating system with POSIX compatibility and
7938-407: Was announced as the successor to Windows 10 during a livestream. The new operating system was designed to be more user-friendly and understandable. It was released on October 5, 2021. As of May 2022, Windows 11 is a free upgrade to Windows 10 users who meet the system requirements. In July 2021, Microsoft announced it will start selling subscriptions to virtualized Windows desktops as part of
8036-492: Was available in a number of different editions , and has been subject to some criticism , such as drop of performance, longer boot time, criticism of new UAC, and stricter license agreement. Vista's server counterpart, Windows Server 2008 was released in early 2008. On July 22, 2009, Windows 7 and Windows Server 2008 R2 were released to manufacturing (RTM) and released to the public three months later on October 22, 2009. Unlike its predecessor, Windows Vista, which introduced
8134-456: Was considered a commercial failure but with technical acclaim, introducing several advanced features that reappeared on the Macintosh and eventually IBM PC compatibles . These include an operating system with memory protection and a document-oriented workflow. The hardware is more advanced overall than the following Macintosh, including hard disk drive support, up to 2 megabytes (MB) of random-access memory (RAM), expansion slots, and
8232-509: Was designed as a modified microkernel , influenced by the Mach microkernel developed by Richard Rashid at Carnegie Mellon University, but without meeting all of the criteria of a pure microkernel. The first release of the resulting operating system, Windows NT 3.1 (named to associate it with Windows 3.1 ) was released in July 1993, with versions for desktop workstations and servers . Windows NT 3.5
8330-410: Was divided among 65 different repositories with a kind of virtualization layer to produce unified view of all of the code. Apple Lisa Lisa is a desktop computer developed by Apple , produced from January 19, 1983 to August 1, 1986, and succeeded by Macintosh . It is generally considered the first mass-market personal computer operable through a graphical user interface (GUI). In 1983,
8428-462: Was marketed in two main editions : the "Home" edition was targeted towards consumers, while the "Professional" edition was targeted towards business environments and power users , and included additional security and networking features. Home and Professional were later accompanied by the "Media Center" edition (designed for home theater PCs , with an emphasis on support for DVD playback, TV tuner cards , DVR functionality, and remote controls), and
8526-526: Was named for my daughter." The project began in 1978 as an effort to create a more modern version of the then-conventional design epitomized by the Apple II . A ten-person team occupied its first dedicated office at 20863 Stevens Creek Boulevard next to the Good Earth restaurant, and nicknamed "the Good Earth building". Initial team leader Ken Rothmuller was soon replaced by John Couch , under whose direction
8624-690: Was not released until November 1985. Windows 1.0 was to compete with Apple 's operating system, but achieved little popularity. Windows 1.0 is not a complete operating system; rather, it extends MS-DOS . The shell of Windows 1.0 is a program known as the MS-DOS Executive . Components included Calculator , Calendar, Cardfile , Clipboard Viewer , Clock, Control Panel , Notepad , Paint , Reversi , Terminal and Write . Windows 1.0 does not allow overlapping windows. Instead, all windows are tiled . Only modal dialog boxes may appear over other windows. Microsoft sold as included Windows Development libraries with
8722-435: Was re-branded MacWorks XL as the primary system application, to convert the Lisa into the Macintosh XL . The launch version of Lisa Office System can not be used for programming, requiring the separate development OS called Lisa Workshop to be toggled and booted. Lisa Workshop was also used to develop Macintosh software for its first few years, until a Macintosh-native development system was released. For most of its lifetime,
8820-491: Was rebranded as Macintosh XL. It was given a hardware and software kit, enabling it to reboot into Macintosh mode and positioning it as the high-end Macintosh. The price was lowered yet again, to $ 4,000, and sales tripled, but CEO John Sculley said that Apple would have lost money increasing production to meet the new demand. Apple discontinued the Macintosh XL, leaving an eight-month void in Apple's high-end product line until
8918-410: Was released in April 2003. It was followed in December 2005, by Windows Server 2003 R2. After a lengthy development process , Windows Vista was released on November 30, 2006, for volume licensing and January 30, 2007, for consumers. It contained a number of new features , from a redesigned shell and user interface to significant technical changes , with a particular focus on security features . It
9016-510: Was released in September 1994, focusing on performance improvements and support for Novell 's NetWare , and was followed up by Windows NT 3.51 in May 1995, which included additional improvements and support for the PowerPC architecture. Windows NT 4.0 was released in June 1996, introducing the redesigned interface of Windows 95 to the NT series. On February 17, 2000, Microsoft released Windows 2000 ,
9114-671: Was released in two different versions: Windows/286 and Windows/386 . Windows/386 uses the virtual 8086 mode of the Intel 80386 to multitask several DOS programs and the paged memory model to emulate expanded memory using available extended memory . Windows/286, in spite of its name, runs on both Intel 8086 and Intel 80286 processors. It runs in real mode but can make use of the high memory area . In addition to full Windows packages, there were runtime-only versions that shipped with early Windows software from third parties and made it possible to run their Windows software on MS-DOS and without
9212-505: Was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families, including the now-defunct Windows 9x , Windows Mobile , Windows Phone , and Windows CE/Embedded Compact . Windows
9310-401: Was roughly equivalent to a service pack . The first OSR of Windows 95 was also the first version of Windows to be bundled with Microsoft's web browser , Internet Explorer . Mainstream support for Windows 95 ended on December 31, 2000, and extended support for Windows 95 ended on December 31, 2001. Windows 95 was followed up with the release of Windows 98 on June 25, 1998, which introduced
9408-582: Was the first client version of Windows NT to be released simultaneously in IA-32 and x64 editions. As of 2024, x64 is still supported. An edition of Windows 8 known as Windows RT was specifically created for computers with ARM architecture , and while ARM is still used for Windows smartphones with Windows 10, tablets with Windows RT will not be updated. Starting from Windows 10 Fall Creators Update (version 1709) and later includes support for ARM-based PCs. Windows CE (officially known as Windows Embedded Compact ),
9506-551: Was used in the Dreamcast along with Sega's own proprietary OS for the console. Windows CE was the core from which Windows Mobile was derived. Its successor, Windows Phone 7 , was based on components from both Windows CE 6.0 R3 and Windows CE 7.0 . Windows Phone 8 however, is based on the same NT-kernel as Windows 8. Windows Embedded Compact is not to be confused with Windows XP Embedded or Windows NT 4.0 Embedded , modular editions of Windows based on Windows NT kernel. Xbox OS
9604-420: Was using Git, in about 8500 commits and 1760 Windows builds per day. In June 2021, shortly before Microsoft's announcement of Windows 11, Microsoft updated their lifecycle policy pages for Windows 10, revealing that support for their last release of Windows 10 will end on October 14, 2025. On April 27, 2023, Microsoft announced that version 22H2 would be the last of Windows 10. On June 24, 2021, Windows 11
