Disable, shutdown Event Tracker
A nice feature that can sometimes by annoying is the Shutdown Event Tracker, that allows you to comment every time you shut off a server.
While I do understand the auditing requirements to have this in place on production server, this feature is unnecessary for development and test servers and can be disabled.
To disable Shutdown Event Tracker we need to open the Group Policy Editor, the Group Policy Editor can be opened from pressing START > RUN > GPEDIT.MSC then press ENTER
From the navigation menu on the left side navigate to "Computer Configuration > Administrative Templates > System", then on the right side double click "Display Shutdown Event Tracker"
Change the option from "Not Configured" to "Disabled" > Press "Apply" then press "OK".
Note you can also use this to enable Shutdown Event Tracker in Vista although I have no idea why someone would want to do that.
A restart is not required for this change to take effect.
