Several days ago a friend contacted me for help because he couldn’t log on his user account on his Windows 7-based computer, and he received the error message “The User Profile Service failed the logon” and “The user profile cannot be loaded”. Corrupt user profile is a frustratingly common problem. Now I share with you how to fix this problem.
Occasionally, Windows might not read the user profile correctly. You can try to restart the computer and log on with the user account again to resolve the issue. If you restart your computer and it doesn’t resolve this issue, you can follow the method below to resolve this issue.
1. Log on with an Administrator account. If you do not have another Administrator account, then you need to boot into Safe Mode and log on with the built-in Administrator account.
2. Open the Start Menu, type regedit in the search box, and press Enter key. If prompted by UAC, then click on Yes.
3. In regedit, navigate to the location below:
4. 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 problem.
5. If there are two folders starting with S-1-5 followed by some long numbers and one of them ended with .bak, you need to rename these two folders:
a) Right-click the folder without .bak, click Rename, type .ba at the end of the folder name, and then press ENTER.
b) Right-click the folder with .bak, click Rename, remove .bak, and then press ENTER.
c) Right-click the folder that is named .ba, click Rename, change the .ba to .bak, and then press ENTER.
6. If there is only one folder starting with S-1-5 that is followed by long numbers and ends with .bak. Right-click the folder, click Rename, remove .bak, and then press ENTER.
7. Double-click the folder without .bak, and then follow the steps below:
a) In the details pane, double-click RefCount, type 0, and then click OK.
b) Double-click State, type 0, and then click OK.
8. Close Registry Editor and restart the computer, and then log on again with your account.
