I had to completely restore my 2004 HP Pavillion a387x desktop which is
running XP Home.  I used the restore CD, loaded SP2 when that was completed
and reloaded my virus software.  In the process of the restore, I did not
reformat the hard drive so I could keep all of my data files... and users.  
When it was time to configure the desktop after the restore, I re-entered
each user name exactly as they were previously.  When they logged on the
first time the machine hung-up and had to be hard booted.  When I looked at
the file structure, the old users remained in their entirity, and the new
users that had attempted to log on, created new folders (now with an
extention on their name)  and profiles?  Is there any way of pointing the
users profile back to the old profile & sub-folders?  Help....!!!
