Service Pack and Update Center


Get the latest service pack or update for your version of Windows

A service pack (SP) is a Windows update, often combining previously released updates, that helps make Windows more reliable. Service packs, which are provided free of charge on this page, can include security and performance improvements and support for new types of hardware. Make sure you install the latest service pack to help keep Windows up to date. Service packs take about 30 minutes to install, and you'll need to restart your computer about halfway through the installation.

The recommended (and easiest) way to get updates such as service packs is to turn on Windows Update for Windows 8.1, Windows 8, Windows 7, and Windows Vista and let Windows notify you when the updates you need are ready to install. In Windows 10, updates are automatically downloaded unless you're using a metered connection. Learn more about keeping Windows 10 up to date.
