Critical Windows security patches

April 13, 2004

On April 13, 2004, Microsoft released critical patches for multiple Windows security vulnerabilities.

*** ALL Windows PCs must be patched ***

On April 20, we will be begin to automatically push these patches to all hosts in the SCS Windows Domain that run Windows 2000 or Windows XP. Click on the Automatic Updates icon on the Windows taskbar (if present) if you wish to manually install the patches on such hosts before that date.

If your host is not in the SCS Domain, or if you do not have this icon on your taskbar, you should run Windows Update as per the instructions below. If your PC runs an older version of Windows (Windows NT/98/ME), you will also need to manually run Windows Update. You can run Windows Update at any time to scan your PC and verify that all critical patches have been installed.

How to run Windows Update to patch your PC:

  1. Run Internet Explorer (version 5 or higher).
  2. Select "Windows Update" under the "Tools" menu.
  3. Once you have connected to the Windows Update site, select "Scan for updates" (if you are running Windows 2000 or XP).
  4. You should install all "Critical Updates".
  5. You will need to reboot your PC after installation.
  6. Because some updates may depend on previous updates already being installed, you should re-run Windows Update after rebooting to verify that you have successfully installed the patches, and to install any remaining critical updates.

Additional information about these security vulnerabilities can be found at: http://www.microsoft.com/security/security_bulletins/200404_windows.asp (off-site link, will open in a new window).

Please contact help@cs.cmu.edu if there are questions or problems with patching your PC.
