- 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 It succeeded Windows 8.1 and was ultimately superseded by Windows 11 on 5 October 2021.
This is the last version of Microsoft Windows to support the IA-32 architecture (32-bit x86 systems) as Windows 11 requires an x86-64 processor with CMPXCHG16b, PrefetchW and LAHF/SAHF instructions.
Windows as a service[edit | edit source]
With Windows 10, Microsoft introduced a new release model called Windows as a service. Instead of releasing a major version of Windows every few years, the company instead vowed to release smaller updates to Windows 10 multiple times a year. These updates, labeled feature updates to differentiate them from regular bugfixes, are major updates to the operating system that add new features to the operating system. Usually, they are a new build of the operating system released after one or more development cycles. 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. They are released twice in a year, with the first feature update being released in spring and the other in autumn.
