I wanted to get some help as I'm unsure to whether I should go with windows xp home or the pro edition with regards to limiting users access to the computer. I have heard stories from friends that XP home does not have features that allow administrator to lock down most of the features on an OS that a malicious user can use to harm the computer. Such as the format command, regedit, and the almighty ctrl+alt+del. Any suggestions on which OS to use?
