From the "No Not All My Stuff Is Patched Yet" Dept.

This is a public service announcement.

If you have a Windows 2008 R2 server without SP1 or without this hotfix, and you also have a monitoring application or script that uses WMI to query for service information from the Win32_Service WMI class on a regular basis, you might just get burned really badly by a memory leak that will have the WMI service gobbling up >500MB of memory until it crashes.  You might then have to roll back hours of work and hope the Microsoft bug didn't cause any cluster failovers or dropped Exchange mailbox stores across a couple dozen servers.
