Hello, I have very minimal computer knowledge. Now my computer (dell with XP) after pushing the power button on the tower is "on" and after Welcome, I have my desktop. How do I "lock" the computer, so that it cannot be used at all by anyone other than myself? I need specific steps please. Thank you very much in advance.

Go to

Control panel
