Windows Update is a web-based software update service for Microsoft Windows operating systems. It offers a location for downloading critical system component updates, service packs, security fixes, patches and free upgrades to selected Windows components. Additionally, it automatically detects the user's hardware and provides driver updates when available, and can offer beta versions of some Microsoft programs.
The Windows Update feature was in the headlines because of the July 2005-introduced Windows Genuine Advantage (WGA) for users updating any version of Windows XP, Windows Server 2003, and Windows 2000. Treated as an update, the software analyzes the user's computer and determines if their copy of Windows XP is genuine. Critics found that the service is spyware-similar, as it does not explicitly tell users of the data collected on the user's computer and delivered to Microsoft servers.
