Windows Update is a Control Panel applet found in Windows Vista that provides updates for the operating system and related components, such as definition updates to the Windows Defender anti-spyware product and Junk Mail filter updates for Windows Mail.

Microsoft Update is an optional feature in Windows Update that provides updates not only for the operating system, but also certain Microsoft software. It is not enabled by default.

In older versions of Windows, Microsoft Update was a web application. The move away from the web-based paradigm for Windows updates could alleviate the concerns by critics regarding the ability of a web browser to perform trusted update operations on a Windows computer.

A common irritation for Microsoft Update users was that updates requiring a reboot would pop up a dialog box requesting that the user reboot their machine every 10 minutes. This dialog box would also typically be displayed on top of whatever other applications the user was working with at the time. While Windows Update will still require reboots for certain classes of updates, this dialog box was changed to allow the user to select a longer period of time (up to 4 hours) before being prompted again. The revised dialog box also displays under other applications, instead of on top of them.
