How to Force Microsoft Security Updates to Install

by Thomas King

Microsoft Security Center is a free anti-malware program created by Microsoft. In order to protect your computer from the latest malicious programs, Microsoft Security Center must be up to date with the latest virus definitions. These virus definitions are automatically installed periodically through the Windows operating system update feature. However, you may want to force the updates to install before the scheduled automatic update. There are two equally effective ways to accomplish this.

Method One


Click "Start", "All Programs" and "Windows Update". The Windows Update window opens.


Click "Check for Updates" in the left pane of the Windows Update window.


Click "Install Updates". Windows will automatically install the latest updates for Microsoft Security Essentials. This may take several minutes and you may be prompted to restart your computer.

Method Two


Click on the link to download the latest definition updates for Microsoft Security Essentials. Note that there are two options: 32 bit version of Windows and 64 bit version of Windows. Be sure to click the appropriate link.


Click "Save" and save the file to your desktop.


Right-click the file on your desktop and select "Run As Administrator". A file extraction box opens. Once the file extraction box closes, the updates have been installed.
