Is there any way to hide personally identifiable data about your PC (while on-line). For example XP knows your log on name and system name and in system properties lists your registration number (that really long string of about 20 characters). Can I edit a system file or the registry to hide this or change it to another random number. I have already reformatted and my log on and system name are non identifiable but I can't seem to get to the registration number. (before you ask this is a legal non warez version of windows that I own, I just like being anonymous online)
