How-To: Install Microsoft Service Packs

Microsoft Service Packs

A service pack (SP) is a Microsoft update for Windows or Office, often combining previously released updates, that helps make Windows and Office more reliable. Service packs, which are provided free of charge from Microsoft, 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 and Office up to date. Service packs take about 30 minutes to install.
