Windows server 2003 logon and shut down annoyances fixed!

Something that I have found very annoying with Windows Server 2003 is that it asks you for a reason why you want to shut down, and also that it won't let you shut down the machine before logging in. I can understand why in large business environments this behaviour would be useful but for the way we use it at work it's just a PITA.
Finally remembered to try and resolve it this morning and quickly came across a great post from
Thomas Freudenberg's blog here. Which kills both birds with one stone.
