desktop background

Ah well, this can be changed but you need to go digging in the registry, which I would clearly never do.

Also, if you then set the wallpaper through Firefox or MSIE then it will work as the control panel interface remains disabled via the group policy. Again, a registry key controls whether you see the wallpaper tab in display properties.

It is useful to have different wallpapers for different users as this then is a quick way of seeing if you are the logged in user as your desktop is immediately identifiable.

Not sure if changes I make locally will persist on reboot and relogin though. Find out tomorrow.
