Microsoft Windows is a computer operating system developed by Microsoft. It was first launched in 1985 as a graphical operating system built on MS-DOS. The initial version was followed by several subsequent releases, and by the early 1990s, the Windows line had split into two separate lines of releases: Windows 9x for consumers and Windows NT for businesses and enterprises. In the following years, several further variants of Windows would be released: Windows CE in 1996 for embedded systems; Pocket PC in 2000 (renamed to Windows Mobile in 2003 and Windows Phone in 2010) for personal digital assistants and, later, smartphones; Windows Holographic in 2016 for AR/VR headsets; and several other editions.
Personal computer versions[edit]
A «personal computer» version of Windows is considered to be a version that end-users or OEMs can install on personal computers, including desktop computers, laptops, and workstations.
The first five versions of Windows–Windows 1.0, Windows 2.0, Windows 2.1, Windows 3.0, and Windows 3.1–were all based on MS-DOS, and were aimed at both consumers and businesses. However, Windows 3.1 had two separate successors, splitting the Windows line in two: the consumer-focused «Windows 9x» line, consisting of Windows 95, Windows 98, and Windows Me; and the professional Windows NT line, comprising Windows NT 3.1, Windows NT 3.5, Windows NT 3.51, Windows NT 4.0, and Windows 2000. These two lines were reunited into a single line with the NT-based Windows XP; this Windows release succeeded both Windows Me and Windows 2000 and had separate editions for consumer and professional use. Since Windows XP, multiple further versions of Windows have been released, the most recent of which is Windows 11.

Device versions[edit]
ARM-based tablets[edit]
Windows RT logo
The Surface RT (shown with keyboard cover attached) was the flagship Windows RT device upon its release.
In 2012 and 2013, Microsoft released versions of Windows specially designed to run on ARM-based tablets; these versions of Windows, named «Windows RT» and «Windows RT 8.1,» were based on Windows 8 and Windows 8.1, respectively. Upon the release of Windows 10 in 2015, the ARM-specific version for large tablets was discontinued; large tablets (such as the Surface Pro 4) were only released with x86 processors and could run the full version of Windows 10. Windows 10 Mobile had the ability to be installed on smaller tablets (up to nine inches);[26] however, very few such tablets were released, and Windows 10 Mobile primarily ended up only running on smartphones until its discontinuation. In 2017, the full version of Windows 10 gained the ability to run on ARM, thus rendering a specific version of Windows for ARM-based tablets unnecessary.

|---|---|---|---|---|---|
| Cairo | — | 1996 | NT 4.0 | 1175 | Originally announced at the 1991 Microsoft Professional Developers Conference, Cairo was the codename of a project whose charter was to build technologies for a next-generation operating system that would fulfill Bill Gates’s vision of «information at your fingertips».[30] Cairo never shipped, although portions of its technologies have since appeared in other products. |
| Nashville[t] | Windows 96 | 1996 | 4.1 | 999 | Nashville was an operating system planned to have been released between Windows 95 and Windows 98, presumably under the «Windows 96» moniker. |
| Neptune | — | Early 2000 | NT 5.50 | 5111 | Neptune, based on the Windows 2000 codebase, was planned to be the first version of Microsoft Windows NT to have a consumer edition variant. A version was sent out to testers but was never released.[31] The teams working on Neptune and Odyssey eventually combined to work on Windows XP. |
| Odyssey | — | Early 2000 | NT 6.0[32] | — | Odyssey was planned to be the successor of Windows 2000. The teams working on Neptune and Odyssey eventually combined to work on Windows XP. |
| Triton | — | Early 2000 | — | — | Triton was planned to be the successor of Windows Neptune and had been scheduled to be released in March 2001. |
| Blackcomb | — | 2006-01 | — | — | Blackcomb was originally planned to be a release of Windows following Windows XP. However, due to the large feature scope planned for Blackcomb, a smaller release codenamed «Longhorn» was planned first, and Blackcomb was delayed to 2003/2004. Both projects faced delays; Longhorn would go on to be released to consumers as «Windows Vista» in January 2007, while development on Blackcomb continued until the Blackcomb project was renamed «Vienna» in early 2006. |
| Vienna | — | 2007-07[u] | — | — | Vienna replaced Blackcomb and was intended as Windows Vista’s successor. Vienna was eventually cancelled in favor of a new project codenamed «Windows 7» (which went on to be released in 2009 with the same name). |
| Polaris | — | 2018 | — | 16299 | Cancelled in favor of Santorini |
| Santorini[v] | Windows 10X | 2021-05-18[w][34] | 21H1 | 20279 | Microsoft had been reported as working on a new «lite» version of Windows as early as December 2018.[35] Such a version was officially announced under the name «Windows 10X» at an event in October 2019; the operating system was intended to first launch on dual-screen devices. In May 2020, Microsoft announced that Windows 10X would instead be launching on single-screen PCs, such as laptops and 2-in-1 devices, first.[36] However, on May 18, 2021, Microsoft announced that Windows 10X would not be launching (at least not in 2021); many of its features were instead rolled into Windows 11. |

- ^ Windows 10 versions 1507 and 1511 do not include a «Windows 10 Pro Education» edition; that edition was only added with version 1607.
- ^ Windows 10 S is only available in version 1703 and 1709.
- ^ Windows 10 Enterprise LTSC is only available for versions 1507, 1607, 1809, and 21H2. It had originally been named Windows 10 Enterprise LTSB in version 1507.
- ^ October 14, 2025 is the general end-of-support date for Windows 10. Specific versions and editions of Windows 10 have different end of support dates; see Windows 10 version history for a breakdown of dates by version and edition.
- ^ Originally codenamed 19H2[14]
- ^ Vibranium was the codename for Windows 10 version 2004. During the 20H2, 21H1, and 21H2 development cycles, builds were compiled under the codenames Manganese, Iron, and Cobalt, respectively. However, the versions of 20H2 and 21H1 that were released were built on top of version 2004 instead of these new builds. Windows 10 version 21H2 was similarly built on top of the Vibranium/2004 codebase instead of the Cobalt codebase; Cobalt builds were instead used as the base for the first version of Windows 11 (which had a core based on Cobalt in addition to a UI codenamed Sun Valley, and which also carries the version 21H2).
- ^ The core of Windows 11 version 21H2 is codenamed Cobalt;[17] the «Sun Valley» codename refers to the UI layer of Windows 11 version 21H2 and is commonly used to address Windows 11 version 21H2 as a whole.

- ^ Nashville was originally codenamed Cleveland.
- ^ July 2007 is when it was reported that the Vista’s successor was codenamed «7», rather than «Vienna», indicating that Vienna’s discontinuation had occurred by then. However, Vienna may have been cancelled prior to then.
- ^ While Santorini was the general codename for Windows 10X, Centaurus was the specific codename for Windows 10X on foldable PCs and Pegasus was the codename for Windows 10X on «traditional» PCs (such as laptops or 2-in-1 computers).[33]
- ^ a b Date refers to when the cancellation of the operating system was announced. The decision for the operating system to be cancelled may have occurred prior to then.

Guide to Windows version numbers and major Windows builds
Updated on September 20, 2022
Each Microsoft Windows operating system has a familiar name, such as Windows 11 or Windows Vista, but behind each common name is an actual Windows version number1.
Windows Version Numbers
Below is a list of major Windows versions and their associated version numbers:
| Reference Table for Windows Version Numbers | ||
|---|---|---|
| Operating System | Version Details | Version Number |
| Windows 11 | Windows 11 (22H2) | 10.0.22621 |
| Windows 11 (21H2) | 10.0.22000 | |
| Windows 10 | Windows 10 (21H2) | 10.0.19044 |
| Windows 10 (21H1) | 10.0.19043 | |
| Windows 10 (20H2) | 10.0.19042 | |
| Windows 10 (2004) | 10.0.19041 | |
| Windows 10 (1909) | 10.0.18363 | |
| Windows 10 (1903) | 10.0.18362 | |
| Windows 10 (1809) | 10.0.17763 | |
| Windows 10 (1803) | 10.0.17134 | |
| Windows 10 (1709) | 10.0.16299 | |
| Windows 10 (1703) | 10.0.15063 | |
| Windows 10 (1607) | 10.0.14393 | |
| Windows 10 (1511) | 10.0.10586 | |
| Windows 10 | 10.0.10240 | |
| Windows 8 | Windows 8.1 (Update 1) | 6.3.9600 |
| Windows 8.1 | 6.3.9200 | |
| Windows 8 | 6.2.9200 | |
| Windows 7 | Windows 7 SP1 | 6.1.7601 |
| Windows 7 | 6.1.7600 | |
| Windows Vista | Windows Vista SP2 | 6.0.6002 |
| Windows Vista SP1 | 6.0.6001 | |
| Windows Vista | 6.0.6000 | |
| Windows XP | Windows XP2 | 5.1.26003 |
[1] More specific than a version number, at least in Windows, is a build number, often indicating exactly what major update or service pack has been applied to that Windows version. This is the last number shown in the version number column, like 7600 for Windows 7. Some sources note the build number in parenthesis, like 6.1 (7600).
[2] Windows XP Professional 64-bit had its own version number of 5.2. As far as we know, that’s the only time Microsoft has designated a special version number for a specific edition and architecture-type of a Windows operating system.
[3] Service pack updates to Windows XP did update the build number but in a very minor and long-winded way. For example, Windows XP with SP3 and other small updates is listed as having a version number of 5.1 (Build 2600.xpsp_sp3_qfe.130704-0421 : Service Pack 3).
How to Update Windows
To update Windows to the newest build number, use Windows Update. The built-in Windows Update utility is the easiest way to check for and install Windows updates.
If you haven’t set up your version of Windows to install updates automatically, you can change the Windows Update settings so that new updates are downloaded and applied automatically. It’s the simplest way to keep Windows updated to the latest version number.
Major Changes in Windows 10
Microsoft introduced several changes to the Windows operating system with Windows 10. These are some of the most significant differences between Windows 10 and Windows 8 (and older versions of Windows):
- Cortana comes built-in to Windows 10
- Microsoft Edge is pre-installed as a replacement browser for Internet Explorer
- Brand-new versions of Mail, Calendar, Maps, and Photos
- Expanded notifications are available through Windows Action Center
- User interface that works well with both touch screen displays and traditional monitors that use a keyboard and mouse
- Windows 10’s Start menu replaces the full-screen Windows 8 Start Screen
- Microsoft Paint 3D replaces Microsoft Paint
- Share files wirelessly with other PCs using Windows Nearby Sharing
- Set quiet hours by blocking notifications with Windows Focus Assist
- Windows Hello lets you log in to Windows 10, apps, and websites with your face
- Play Xbox One games on your Windows computer

Можно отфильтровать вывод утилиты:
systeminfo | findstr /B /C:"OS Name" /B /C:"OS Version"
Или воспользуйтесь WMI командой:
wmic os get Caption, Version, BuildNumber, OSArchitecture
Аналогом команды systeminfo в PowerShell является командлет Get-ComputerInfo:
Get-ComputerInfo | select OsName, OsVersion, WindowsVersion, OsBuildNumber, OsArchitecture
Главный недостаток командлета Get-ComputerInfo – он выполняется довольно долго. Если вам нужно быстро узнать версию и билд Windows из скрипта PowerShell, лучше воспользоваться одной из следующий конструкций.
Версия Windows в переменной окружения:
[System.Environment]::OSVersion.Version
Из WMI класса:
Get-WmiObject -Class Win32_OperatingSystem | fl -Property Caption, Version, BuildNumber
В современных версиях PowerShell Core 7.x вместо командлета Get-WmiObject нужно использовать Get-CimInstance:
Get-CimInstance Win32_OperatingSystem | fl -Property Caption, Version, BuildNumber, OSArchitecture
Значение параметра OSArchitecture позволяет определить установлена ли на компьютере
x86
или
x64
версия Windows.
Можно получить номер билда и версии непосредственно из реестра Windows.
Reg Query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v ProductName
Reg Query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v DisplayVersion
Reg Query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v CurrentBuild
или
Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion"| select ProductName, DisplayVersion, CurrentBuild
С помощью параметров реестра
ProductVersion
,
TargetReleaseVersion
и
TargetReleaseVersionInfo
в ветке HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate вы можете указать версию Windows, до которой ваш компьютер может автоматически обновиться. Эти параметры позволяют также запретить автоматическое обновление ОС до Windows 11.
Вы можете получить информацию о версии Windows на удаленном компьютере через PowerShell Remoting:
Invoke-Command -ScriptBlock {Get-ItemProperty 'HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion' | Select-Object ProductName, ReleaseID, CurrentBuild} -ComputerName wksPC01
Или WMI/CIM:
Get-ciminstance Win32_OperatingSystem -ComputerName wksPC01 | Select PSComputerName, Caption, OSArchitecture, Version, BuildNumber | FL
Если компьютер добавлен в домен Active Directory, вы можете получить информацию о версии/билде Windows на компьютере из атрибутов компьютера в AD (как получить список версий и билдов Windows в домене Active Directory).
