If you're like me, and use Windows 2003 on your desktop, chances are that you may find that dialog box that pops up after every hardboot or at every restart/shutdown only slightly annoying.
Here is how to disable that.
Start->Run type “gpedit.msc” .. hit Enter.
Go to Local Computer Policy -> Computer Configuration -> Administrative Templates -> System ->
In there find “Display Shutdown Event Tracker”, double click and choose “Disabled”.
WALLA !! :-)
And oh yeah, there's tonnes of other stuff there too.
