With Windows XP, it's easier than ever to share a single computer among several users.
Each person using the computer can create a separate password-protected account with personalized settings and private files. Multiple accounts can be active on the computer at the same time—switching back and forth is fast and simple.
For example, if someone wants to check e-mail while you're working, they simply switch over to their account. There's no need for you to close your programs and log off. The other user won't see your files while they're working; and when you switch back you won't see theirs. You'll find the screen exactly as you left it.
