Install Windows updates in Windows 7

If you'd like Windows to install important updates as they become available, turn on automatic updating. Important updates provide significant benefits, such as improved security and reliability. You can also set Windows to automatically install recommended updates, which can address noncritical problems and help enhance your computing experience. Optional updates are not downloaded or installed automatically. To learn more about the types of updates that Microsoft publishes, see Turn automatic updating on or off and Change how Windows installs or notifies you about updates.

What to do when things go wrong

Updating your computer by using automatic updating, or by manually checking for updates, is the preferred way to get updates. Sometimes, however, computer, security software, or connection problems can prevent scanning or installation of updates. When this happens, here are a few things you can try:

  • If you have automatic updates turned on but some updates fail, try scanning for updates manually. This can sometimes fix the problem.

  • Be sure your computer is virus-free and malware-free. Run your antivirus and antispyware scanners before running Windows Update.

  • Close all your programs, and restart your computer. It is possible that another program might be preventing Windows Update from working.

  • Check your Internet connection. Be sure you can visit other websites before running Windows Update. Connection problems can trigger errors that can appear to be caused by other factors.

  • If you know the update you need, such as a service pack or security update, you can search the Microsoft website. Most updates also have a knowledge base article (KB) that explains the update, and most updates provide instructions on how to download and install manually.

  • If you continue to see errors, see this automatic troubleshooter on the Microsoft Support website, or go to the Microsoft Answers website for more assistance.
