Hello. I just like to know is there a better way to lock Windows XP so that when i leave the computer no one can tamper with it! I know of the combination of the 'Windows Key' and 'L' to lock it which is okay, but theres the 'Turn Off Computer' button which is what i dont want since even though the computer will be locked, someone can still turn it off! So is there a better way to do it! I remember Windows 2000 had a good locking system so is it possible that Windows XP has it also?
