Windows 10: User profile service failed the sign in

HiMy son is trying to log into his PC and is getting the error above. I’ve tried a couple of troubleshooting suggestions however, we cannot get the command prior to appear, which then allows us to do further trouble shooting. We cannot get beyond the profile login page to enter his pin.Any help would be greatly appreciated.Thanks Louisa

The User Profile Service service failed the sign-in. User profile cannot be loaded.

Hello,

When attempting to login to my computer, I get the following message:

"The User Profile Service service failed the sign-in.

User profile cannot be loaded."

I referred to this Help article,You receive a "The User Profile Service failed the logon” error
message,

but the only difference is I only have one user profile on this computer. So, I can't login with another user to go through the steps listed in this post.

Any suggestions?

Thanks,

User Profile Service Service failed! User profile cannot be loaded.

Brink:
I am using registry editor from command prompt. Drilled down to c:windows\system32\config inside the Load Hive dialog window. Have selected (checked box) the SAM file; clicking on Open opens error message that says:


SAM
This file is in use.
Enter a new name or close the file that's open in another program.

I am at a loss, since I am not running any other program!

Any suggestions?

The SAM file is listed as being 64KB file size.
