I would lke to turn off fast user switching to increase security, but I have two questions.
1) If I do this, will my McAfee services keep themselves running? All of them?
2) Is there any way I can keep my desktop running, like hibernation mode, but just at the login screen if I have the fast user switching turned off?

Thanks guys.

1) The mcafee services should keep running, and some security software you have to have fast user switching off.
2) You can still go into hibernation mode from the Welcome screen: just clik Turn off computer and then hold shift and click hibernate when it appears.

Thanks, upgrader.
