Want to change the Windows Update settings on your Windows Server 2003 but the options are greyed out? You can change them in the registry.
Go to Start> Run> regedit
Go to HKLM> Software> Policies> Microsoft> Windows> WindowsUpdate> AU
To turn off Windows Updates completely, change NoAutoUpdate to 1.
To select one of the other 3 options change AUOptions to either 2, 3 or 4 (Notify=2, Download=3, Automatic=4).
Close and you’re done!
