At one job I spent a lot of time trying to circumvent the helpdesk. Did you know that if network policy forbids you to have automated login after a reboot, you can still do it? Just make a script that sets the correct registry keys, and use the feature where you can run scripts on computer shutdown. The network won't have time to overwrite the registry again. Even the power saving settings of the computer were "administrator only", and we had hundreds of PCs displaying flashy screensavers all night long, because the users didn't want to wait for startup in the morning. Rule no 1: if you forbid something, make sure you have a really good explanation why.
