I have Windows 7 x64 Professional. I love the convenience of not having to log in every time I want to use my computer. However, my awesome rig keeps getting abused by my family for Facebook and word processing. I can't physically kick anyone off. I need to use the rig for school and play, and have every right to it, as the entire rig is wholly paid for and owned by me. I want to lock them out on the fly to prevent my rig from having to endure this tragedy. Restarts should not restore access to the desktop. There's another geek in the house that will probably be able to circumvent the standard procedure, too.
