Hey I'd like to point out another way for this. To pop up cmd hit "windows key+r" then type in "cmd". This comes up with the standard command window. Type in "net user add/ (user name) (password)". This gives you a completely new user that only you know with a password you know. This makes it harder to track who is doing the adding. This however just gives you a new user with basic privileges. So type in "net localgroup Administrator add/ (user)" with (user) being the new user you just created. You now have a Admin user on THAT COMPUTER ONLY. This is somewhat limited but lets you download and run programs and such on a restricted computer/network. This also mean that to discover this new user they have to get on that specific computer and this is a pain in a school or work setting. Enjoy!
