NTUSER.DAT files are the HKEY_CURRENT_USER hive for the registry. They are logs of changes that have been made to the user registry hives (ntuser.dat). They are usually hidden files, but you should keep them.
One NTUSER.DAT for each user on the machine, some templates and repair.
C:\Documents and Settings\Administrator
C:\Documents and Settings\Default User
C:\Documents and Settings\LocalService
C:\Documents and Settings\NetworkService
C:\Documents and Settings\Your Name Here\NTUSER.DAT
C:\WINDOWS\repair
C:\WINDOWS\SYSTEM32\CONFIG\systemprofi…
If the file attributes say they are hidden and you can see them, then hidden files and folders must have been made visible in Control Panel > Folder Options. Re-hide them there.
I would suggest that you leave any NTUSER.DAT files alone. NTUSER.DAT files are essential.
Hope, this works out for ya, RedneckDude.
