The Automatic Updates Service May Stop Responding

If your Windows Server 2003 or Windows XP computer is configured to check for WSUS updates very frequently (say, every 2 hours) the Windows Automatic Update Service (wuauserv.exe) will consume too much memory over time and will eventually become unresponsive.

Microsoft released a hotfix for this situation, which is available at KB914810.  You should only apply this hotfix to affected systems.  This hotfix requires a restart.
