Windows is a series of operating systems developed by the Microsoft Corporation.
Windows 11 is the latest version and is a free upgrade for existing Windows 10 users,
but only if your computer meets the
hardware specifications
and it has one of the
supported processors.
To check this, Open Settings
, select System and click on About.
Otherwise, Windows 10 is the current release, and while updates will continue to be released, support for ALL editions will end on 14 October 2025, although some editions are expected to end sooner than that.
Windows 10 has 12 editions, and Windows 11 has 7 editions, but you are only likely to encounter some of them:
- Windows 10/11 Home is designed for use in PCs, tablets and 2-in-1 PCs. It includes all features directed at consumers.
- Windows 10/11 Pro includes all features of Windows 10/11 Home, with additional capabilities that are oriented towards professionals and business environments.
- Windows 10/11 Pro for Workstations is designed for high-end hardware for intensive computing tasks and supports Intel Xeon, AMD Opteron and the latest AMD Epyc processors.
- Windows 10/11 Enterprise provides all the features of Windows 10/11 Pro, with additional features to assist with IT-based organizations.
- Windows 10 S is a feature-limited edition of Windows 10 designed primarily for low-end devices in the education market, but was discontinued in 2018.
However many new laptop computers are still being sold with this edition pre-installed - best avoided.
- Windows 11 S is a feature-limited edition of Windows 11 designed primarily for low-end devices with limited number of apps and only those available from the Windows Store.
Many new low-specification computers are being sold with this edition pre-installed, but it can be upgraded to Windows 11 Home.
The following table shows the version history of Microsoft Windows for Home, Pro and Pro for Workstation editions, together with the release date,
the end date for mainstream support, and the major updates. Support for Enterprise customers is approximately 1 year after the dates shown.
If you are unsure what version of Windows is running on your computer, press the Windows Key
and the R key at the same time, and then type "
winver" into the small Run window that appears and press Enter or click OK.
Alternatively, go to Settings, select "Update and Security" and click on "
OS build info" under Related links and look for "
Windows specifications".

Information for versions
with release date shown in cyan is tentative, and therefore
subject to change. The value shown in parenthesis () is Microsoft's internal code name which is often used by technical sites when referring to a particular Windows release.
Only the Windows versions
with support date shown in green are currently supported
by Microsoft, and your computer should automatically update to the latest version when Microsoft determines it is ready, although you can request it from Windows Update.
If you are still running an earlier version of Windows
with support date shown in pink,
these are no longer supported, although some Windows security updates which also apply to those versions are still being released for some of them.
