Critical Windows Security Patches

Subject: Critical Windows Security Patches

October 13, 2005

On October 11, 2005 Microsoft released new patches for critical Windows security vulnerabilities.

*** All Windows PCs must be patched. ***

To patch your PC:

Over the next week 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. In the event that these vulnerabilities become widely exploited, we may need to perform emergency patching and unscheduled reboots of un-patched systems.

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, 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.
If you do not have such an icon, run Windows Update by going to the site:

Please contact if there are questions or problems with applying these patches.

Thank you for your attention,
