Questions tagged [windows-update]

Windows Update (WU), a service offered by Microsoft, provides updates for the Microsoft Windows operating system and its installed components, including Internet Explorer. This tag should be used exclusively for programming questions, not general issues with Windows updates or the Windows operating system; these questions should be directed to Super User instead.

Windows Update includes the following:

  • The Windows Update (WU) Service offered by Microsoft, which provides updates for Microsoft Windows operating systems.
  • The Windows Update Agent (WUA) which perform the communications with WU, searching for updates and install updates.
  • Windows Automatic Updates (AU) which schedule automatic, notifications, downloads, and installations of Updates. "Windows Update and Automatic Updates are two separate components designed to work together to keep Windows secure. " See, How to configure Automatic Updates and Difference between Windows Update and Automatic Updates
  • The WUA API, which enables programmers and administrators to manage WU updates on the local system. See WUA API reference.
