Patches and other security updates are routinely released through Windows Update on the second Tuesday of every month—it’s called Patch Tuesday. However, Microsoft releases updates on other days as well, like for urgent fixes.

What Is Windows Update Used For?

Windows Update is used to keep Microsoft Windows and several other Microsoft programs updated.

Updates often include feature enhancements and security updates to protect Windows from malware and malicious attacks.

You can also use Windows Update to access the update history that shows all the updates that have been installed to the computer through the Windows Update service.

Windows Update Availability

All modern Windows operating systems use Windows Update, like Windows 11 and Windows 10, but also the other versions through Windows XP.

However, this service doesn’t update most of your other, non-Microsoft software. You’ll need to update those programs yourself or use a free software updater program to do it for you.

How to Access Windows Update

How you access Windows Update depends on which Windows operating system you’re using:

Windows 11 and Windows 10: Windows Update is part of Settings, available from the Start menu.

Windows 8, Windows 7, and Windows Vista: Windows Update is integrated as a Control Panel applet and is accessible from within Control Panel.

Windows Update can also be accessed in Windows Vista and newer by executing this command from the Run dialog box (WIN+R).

control /name Microsoft.WindowsUpdate

Windows XP, 2000, ME, 98: In older Windows versions, Windows Update is accessible using the Windows Update website through Internet Explorer.

See How to Check For and Install Windows Updates if you need more specific instructions.

How to Use Windows Update

After opening Windows Update as described above, the list of available updates, customized to your specific computer, is shown.

Select the updates you wish to install and follow any instructions given to download and install the updates. Most of the process is entirely automated and might require just a few actions on your part, or you’ll be prompted to restart the computer after the updates are finished installing.

Older Versions of Windows Update

The Critical Update Notification tool (which was later renamed to Critical Update Notification Utility) is a tool Microsoft released around the time of Windows 98. It runs in the background and notifies you when a critical update is available through Windows Update.

That tool was replaced by Automatic Updates, which is available in Windows Me and Windows 2003 SP3. Automatic Updates allows updates to be installed without having to go through a web browser, and it checks for updates less frequently than the Critical Update Notification tool.

More Information on Windows Update

Since Windows Vista, updates may have the .MANIFEST, .MUM, or .CAT file extension to indicate a manifest file, Microsoft Update Manifest file, or security catalog file.

See our guide on How to Fix Problems Caused by Windows Updates if you suspect that a patch is the source of an error message or other problem.

Some non-Microsoft programs, like OUTDATEfighter, install Windows updates if you don’t want to use Windows Update.

Windows Update is not the same utility as Microsoft Store (previously called Windows Store), which is used to download music and apps. See How to Update Apps on Windows 11 for help updating software obtained through Microsoft Store.

Although Windows Update can update some device drivers, many aren’t provided by Microsoft. These might include anything from a video card driver to a driver for an advanced keyboard, in which case you’ll want to update those drivers yourself. One really easy way to download and install drivers without using Windows Update is through a free driver updater tool; some are basically hands-off and automatic, like Windows Update.

Conclusion:

Windows Update is a critical tool for maintaining the health, security, and functionality of your Windows device. Regularly checking for and installing updates ensures your system stays optimized, secure, and compatible with the latest software and hardware standards.
