Windows 10


 * ''This article is about the operating system series developed since 2014. See Windows 10 (original release) for the original operating system release called "Windows 10".

Windows 10 is a series of Microsoft Windows operating systems, initially released in July 2015 after being announced in September 2014. It succeeded Windows 8.1 and was ultimately superseded by Windows 11 in 2021. This version introduced a new release model called Windows as a service with smaller and regular feature updates instead of releasing a major version of Windows every few years. Usually, such updates are a new build of the operating system, however, on multiple occasions, a limited set of new features has been released as a cumulative update and labeled as a new Windows 10 feature update.

Originally, feature updates were released twice in a year, with the first feature update being released in spring and the other in autumn. The schedule was realigned in 2021 in that feature updates for Windows 10 would be released annually in order to be consistent with Windows 11's new release cadence.
