User Profile Service Failed The Logon, Fixed

There are many tutorials on this particular issue online and they all say the same thing. Their methods work pretty well. All the videos and articles all have an identical procedure. If you follow their instructions step by step, you will be able to resolve this issue. Click here to see Microsoft’s support solution.

However, I had a peculiar issue. In the tutorials, it is stated that you have to reboot your computer to safe mode and modify the registry value of your profile. In this particular case, the safe mode had the same login error. This means at that point the tutorials online wouldn’t help you. If this happens in your case, hold on before you think of reformatting you computer.

If you have multiple accounts on your computer, check to see if any of them don’t have the login error. If there’s a working profile, you’ll use that account to modify the profile registry. But if all the profiles are affected by the same error, then you’ll have to find a way to create a new account.

If you’re using a computer joined to a Windows domain, you’ll have to switch to a local account or ask your domain administrator to help with a local account.

If you have a computer with a single account, you may need a third-party application to create a new Windows Admin account or unlock the Administrator account. Try the Hiren BootCD 10. Once you have a new account that you can work with, then you’re ready to fix this issue.

  1. Click Start, type regedit in the Search box, and then press ENTER.
  2. In Registry Editor, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList 
  3. In the navigation pane, locate the folder that begins with S-1-5 (SID key) followed by a long number.Click each S-1-5 folder, locate the ProfileImagePath entry in the details pane, and then double-click to make sure that this is the user account profile that has the error.


  1. Delete the whole entry on the navigation pane for just the affected profile(s)
  2. Restart you computer and try logging in again. It should work normally.

I have read some articles online that say the cause of this problem or the corrupt file is within the user profile folder. I strongly think that’s false. This is because I have renamed the whole user profile and tried to log in just so Windows could recreate a new profile with the same name but the error still remained. I also moved the affected profile folder away from the user folder and it was still the same.
