Windows 10


 * ''This article is about the operating system series developed since 2014. See Windows 10 (original release) for the original operating system called "Windows 10". For a list of Windows 10 builds that are not tied to a specific release, see List of Windows 10 post-20H1 builds.

Windows 10 is a series of Microsoft Windows operating systems, initially released in July 2015 after being announced in September 2014. It will be succeeded in possibly October of 2021 by Windows 11.

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.

Windows as a service
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.
