If you do not have your Windows Automatic Update feature configured to automatically install updates, it is imperative that you visit the Microsoft website to download and install all recommended updates.

If you are using Internet Explorer, you can automatically download all important security updates at update.microsoft.com/microsoftupdate/. The Microsoft Update Center will determine which updates your system requires.

If you are using another browser, go to the Microsoft Download Center at www.microsoft.com/downloads/. Under the New Downloads box, click More. You will see a page of updates listed by release date. The security updates all begin with the words "Security Update." You will need to determine which updates are appropriate for your system.

Note: Many of these patches require that you restart your computer.
