When I installed Win7, I picked ABC as my username. Is it possible to change it to say XYZ? I went to Control Panel, User Accounts and changed the name. On the screen it now shows XYZ, but in the hard drive, everything is still under ABC. For example: C:\Users\ABC\AppData\Local\Temp\sample-file.txt What I like to see is: C:\Users\XYA\AppData\Local\Temp\sample-file.txt Is this possible?
