Windows Update (WU), a service offered by Microsoft, provides updates for Windows components. It can be replaced with Microsoft Update , an expanded version of the service which provides for other Microsoft software as well, such as Microsoft Office, Windows Live Essentials and Microsoft Expression Studio.
