What is Fast User Switching?

Applies to: Home Basic, Home Premium, Business, Enterprise, Ultimate. Which edition of Windows Vista am I using?

Fast User Switching is a feature in Windows that allows you to switch to a different computer user account without closing programs and files first. This makes it easier to share a computer with others. Fast User Switching is turned on by default.

If you turn off the computer while someone else still has programs running, their unsaved files will be lost.
