Windows MultiPoint Server
Main article: Windows MultiPoint Server

Windows MultiPoint Server was an operating system based on Windows Server. The final release of the operating system was Windows MultiPoint Server 2012; it was succeeded by the MultiPoint Services role in Windows Server 2016. Beginning with Windows Server version 1803, Microsoft announced that the MultiPoint Services role was no longer being developed.

Device versions

ARM-based tablets
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 were based on Windows 8 and Windows 8.1, respectively, although the standard versions could run on x86-based tablets without modification. 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 eight inches); however, very few such tablets were released, and Windows 10 Mobile mainly ended up only running on smartphones until its discontinuation. In 2017, the full version of Windows 10 gained the ability to run on ARM, rendering a specific version of Windows for ARM-based tablets unnecessary.

NeptuneEarly 2000NT 5.505111The first planned version of Microsoft Windows NT to have a consumer edition variant, based on the Windows 2000 codebase. A version was sent out to testers but was never released.[26] The teams working on Neptune and Odyssey combined to work on Windows XP.
OdysseyEarly 2000NT 6.0[27]Planned to be the successor of Windows 2000. The teams working on Neptune and Odyssey combined to work on Windows XP.
TritonPlanned to be the successor of Windows Neptune and had been scheduled to be released in March 2001
BlackcombEarly 2006Blackcomb was originally planned to be the successor of 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, but Blackcomb was still intended to be Longhorn's successor until the Blackcomb project was renamed Vienna in early 2006. Longhorn would go on to be released to consumers as "Windows Vista" in January 2007.
ViennaJuly 2007[lower-alpha 17]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)

Santorini[lower-alpha 18]Windows 10XMay 18, 2021 (cancellation announcement)[29]21H120279 Microsoft had been reported as working on a new "lite" version of Windows as early as December 2018.[30] 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.[31] However, on May 18, 2021, Microsoft announced that Windows 10X would not be launching (at least not in 2021); many of its features were rolled into Windows 11 instead.

  4. Windows 7 originally had the build number 7600 when it was released in 2009; the build number was increased to 7601 with the release of Service Pack 1 in 2011.
  5. Announcement date
  6. Retroactively referred to as Threshold 1
  7. Early preview builds of Windows 10 had the version number NT 6.4.[6]
  8. Retroactively referred to as version 1507
  9. Windows 10 Pro for Workstations became a Windows 10 edition starting with version 1709. Prior versions of Windows 10 do not include this as an edition.
  10. Windows 10 versions 1507 and 1511 do not include a "Windows 10 Pro Education" edition; that edition was only added with version 1607.
  11. Windows 10 S is only available in version 1703 and 1709.
  12. 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.
  13. 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.
  14. Vibranium was the codename for Windows 10 version 2004 (build 19041). 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 Windows 11 (which had a core based on Cobalt in addition to a UI codenamed Sun Valley, and which also carries the version 21H2).
  15. The core of Windows 11 is codenamed Cobalt;[15] the "Sun Valley" codename refers to the UI layer of Windows 11 and is commonly used to address Windows 11 as a whole.
  16. Nashville was originally codenamed Cleveland.
  17. 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.
  18. 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).[28]
