Fixing a 'Failed User Service Profile' error in Windows 7

squiggleboldXL

You might see the error message 'The User Profile Service failed the logon. User profile cannot be loaded.'

This can happen when Windows can't read your profile, like when an antivirus program is scanning your computer. This guide will help fix this problem.

 

Load the backup profile from the Registry

1.

Start your computer in Safe Mode. When your computer is starting up, tap the F8 key every second. The 'Advanced Boot Options' menu will open. Choose Safe Mode or Safe Mode with Networking using the arrows, and press ENTER.

2.

In Safe Mode, open the Start menu, type in 'regedit', then click that option.

3.

Use the left hand menu to go to HKEY_LOCAL_MACHINE > Software > Microsoft > WindowsNT > CurrentVersion > ProfileList.

4.

Under 'ProfileList' are folders starting with 'S-1-5', followed by a list of numbers. One of these contains the wrong settings that need to be fixed. To find the broken one, look for two folders that have the exact same name, except one ends with '.bak'.

5.

Right-click the folder without the .bak, and choose Rename. Add .ba to the end of the folder name.

6.

Right-click the folder with the .bak, and choose Rename. Remove the .bak from the end of the folder name.

7.

Right-click and choose Rename on the first folder that you changed to .ba, and change it to .bak.

8.

Click the folder than doesn't end with .bak. In the right-hand window, double-click RefCount, and change the value to 0.

9.

Double-click State, and change the value to 0.

Close the Registry Editor and restart your computer or laptop. The user account should now work normally.

Copy files to the new user profile

After you create the new profile, you can copy over files from the existing profile.

Log on to the computer using the new profile.

2.

Open File Explorer, sometimes referred to as 'Windows Explorer'.

3.

Click Organize, then click Folder and Search Options.

4.

Click the View tab, and click Show hidden files, folders, and drives.

5.

Clear the Hide protected operating system files check box, click Yes to confirm, then press OK.

6.

Find the C:\Users\Old_Username folder, where 'C:' is the drive Windows is installed on, and 'Old_Username' is the profile you want to copy files from.

7.

Highlight all the files and folders, except for 'Ntuser.dat', 'Ntuser.dat.log', and 'Ntuser.ini'.

8.

Click Organize, then click Copy.

9.

Find the C:\Users\New_Username folder, where 'C:' is the drive Windows is installed on, and 'New_Username' is the new user profile you created.

Click Organize, and click Paste.

All the files will move over to the new profile. The old profile can be deleted through the Control Panel.
