How to fix "Windows cannot load the user's profile but has logged you on with the default profile for the system."
1) Boot to Safe Mode.
2) Follow the Leo Huang procedure, steps 1 through 6.
1. In Search programs and files (Windows 7) area, type in regedit, and press Enter.
2. If prompted click yes,
3. expand the following HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
4. click the
sid[Editor's note: folder (key)] that related to your admin profile (if you not sure, click each sid[folder] and in turn look to the right hand side of registry editor it will show who that sid[folder] is related to one of the registry files should hae in description localhost\admin or something similair)
5. right click the sid and press delete. [Editor: Does he mean the SID binary value or the folder/key? Next time remove the binary value first, and if that doesn't work, remove the folder/key.]
6. restart your machine and log back on with the admin account, this will then rebuild the admin profile... dont worry when it loads and none of your personal settings are saved or files or folders
7. Navigate to C:\Users. You will see two folders related to your username. Open each one and look through it to find out which one is correct.
8. Return to regedit and the folder within ProfileList related to your admin profile. Change ProfileImagePath to the correct folder you identified in step 7. [Editor: Does this need to be done in Safe Mode?]
9. Reboot the computer and the profile should work correctly.
