If you receive the error message that reads User profile service failed the logon Windows 10, User profile cannot be loaded or the user profile service failed the sign-in windows 10 domain, it indicates that your user profile is corrupted or that the files in it are missing.
You won’t be able to login to your Windows 10 with a broken user profile. This error may occur if you or any program has made any changes to your user profile, for example, if you have recently deleted the user profile manually, or after a major Windows Update. In this post, we will show you what you can do to fix the User profile service failed the logon Windows 10 domain issue.
Fix: User Profile Service Failed The Logon Windows 10
It’s worth noting that this error could just occur randomly. Most of the time, a simple restart of the PC would fix it. So, try to restart your computer first and see if the problem persists. If it shows the the user profile service failed the sign-in windows 10 error again, follow the solution below.
We will attempt to make some changes to the registry. Please follow the steps carefully. Incorrectly modifying registry may cause serious problems. If possible, back up your registry before editing.
We will edit the registry in safe mode. So, boot your Windows 10 to safe mode first. If you need help, follow this guide: How to enter safe mode in Windows 10. When you’re in safe mode, follow the steps below.
- Go to Windows search / start menu.
- Type regedit and open it.
- In the registry editor, navigate to the following subkey.
- Under the ProfileList folder, look for folder with name that begin with S-1-5 followed by long numbers. Click on the folder.
- Then, from the right pane, double-click on ProfileImagePath.
- Check if the user profile path shown matches your user profile. If you see multiple S-1-5, check each one of them to find the correct S-1-5 which shows the correct user profile path in ProfileImagePath. Follow the rest of the instruction below.
If you have two S-1-5 folders which have the same name (that both matches your user profile) and one of them ended with .bak in its name, you have to rename it to without .bak.
But, to do this we will have to first rename the other folder that without .bak to something else, because two folders with the same name cannot co-exist. Rename the S-1-5 folder without .bak to something like .123.
Then, on the folder that ended with .bak, remove the .bak from its name.
On the .123 folder you’ve renamed earlier, rename it to .bak.
Now, click on the folder without .bak. In the right pane, double-click on RefCount entry. In the value data, enter 0 and then click OK.
If there is no RefCount entry in the folder, right-click anywhere in the right pane. Select New, then DWORD (32-bit) Value. Name it RefCount, double-click it and enter 0 in the value data.
In the same folder, double-click on State entry and then enter 0 to the value data. If the State entry cannot be found from the folder, create a new DWORD (32-bit) Value and name it State. Then, enter 0 to the value data field.
When you’ve done all the steps above, close the registry editor. Restart your computer. It should be able to boot into Windows 10 normally without the User profile service failed the logon Windows 10 error now.
