The user profile service failed to log on user profile cannot be loaded

Just want to share this fix which was proven to work for both Windows Vista and Windows 7 Operating System.

Log on with another administrator user profile or if you don’t have any other and you are the only user, do the following:

1. Turn off computer
2. Turn on computer and press F8 while you see the DELL logo
3. On the Windows Advanced Options select Safe Mode and log in to your account. You can go ahead and try system restore back to when the computer was still working ok (this works as well), but if you are comfortable enough to navigate on the registry, i recommend that you follow the next step
4. Open the Start Menu and type Regedit on the Start Search field
5. Go to the following entry:
a. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Profile List
6. There you will find the following information:

7. On the “.BAK” file you will find an entry with ProfileImagePath with the name of the user.
8. Delete the repeated entry that does not contain “.BAK”
9. Right click on the other entry and select Rename. Delete the extension .BAK for the original entry.
10. Exit Regedit
11. Restart computer.
