So I set up a drive for someone else then ended up using it myself. Now I've got the wrong name still appearing. I changed it under Control Panel > User Accounts and on the start menu, the right name appears. Also from Start > Computer > System Properties. The computer name and full computer name is the right name but when I go to command prompt for example, it still shows up as C:\Users\"wrongname". Why? Why won't it use the name I have listed?
