1.. Click Start, and then click Run.
2.. Type cmd, and then click OK.
3.. Type cd\, and then press ENTER.
4.. Type cd\user~temp.@01, and then press ENTER.
5.. Type dir /x, and then press ENTER. Note the short file name for the
user account folder. For example, the short file name for "User Name, II."
might be "USERNA~1".
6.. Type ren userna~1 username, and then press ENTER
7.. Type exit, and then press ENTER.
8.. Click Start, and then click Run.
9.. Type %homedrive%\user~tmp.@01\username, and then click OK. This folder
and subfolders should contain the files from the missing user account.
