This guide provides you with information on the latest Windows updates and Service Packs, including where to download them and how to install them.
Microsoft released service packs traditionally for its operating systems, but switched to the new feature upgrade system with the release of Windows 8.
Service Packs are only available for Windows 7 and earlier operating systems on the client side, while Feature upgrades for Windows 8 and newer versions of Windows including Windows 10.
Microsoft supports the following client operating systems currently:
