BleepingComputer.com: Very Odd Request

I was recently asked by a friend to help him remove his guest account on his PC. Not a problem, was easy enough to go in under windows Vista and turn off the account. But he wanted to know if there was a way to completely remove the option for anyone to get on his PC and add a guest account by removing the ability for windows to even create one.

Is there a means to go into the registry and turn something off or change some line of text that removes the guest account from the PC entirely or would that be a terrible idea?

Windows Vista 32 bit home prem.
