Guest accounts on lab computers (Score 1)

I personally do not lock my profiles down for my labs. I used to do this and it was just a waste of time. My preference now is to use guest accounts instead of user accounts. The nice thing about guest accounts is that when you log out they are destroyed, so if they change the background then it makes no difference. I will often redirect the My Documents folder to "c:\temporary work" though or something similar so they can save documents between sessions, although I warn them that they could be wiped at any time. The one caveat to this is that with Windows XP it is now a feature that guest accounts are only guest accounts if the computer is on a domain. However, if you do not have a domain you can join them to a temporary domain and not use it (because the accounts do not need to be domain accounts), but if you have a domain then this works out even easier for you.
