Of course I can't get into Control Panel. They've done a good job actually - the PCs don't have USB ports or floppy/CD drives, so nobody can take data out of the building from their computer. I don't have a say in which wallpaper is displayed or when the machine is defragged (I don't suppose anyone does that, but as it only uses a handful of programs I doubt it's very fragmented).

Actually there's not much loads in startup - the machine seems to take ages to boot because it runs a logon script etc and from two weeks ahead, it halts and asks if you want to change your password. We don't have screensavers loaded.
