Disable Windows Server 2003 Shutdown Event Tracker
I was working in a VPC, installing SharePoint 2007 and the new beta Office tools. The number of reboots wasn't painful or anything, but I am seriously sick of the Windows Server 2003 Shutdown Event Tracker.

A quick look around online and I found that by following these steps I was able to stop myself from unnecessary pain:
- From Window's Start menu, select Run and enter GPEDIT.MSC
- From the Group Policy Object Editor, expand Computer Configuration | Administrative Templates | System
- Double-click Display Shutdown Event Tracker from the System Setting list
- Select the Disabled option button
- Click OK
- Close Group Policy Object Editor
Thanks to Charles Maxson of the Office Zealot blog, particularly this post, for the above answer. I even nicked his screenshot!
