Logon process failed. Windows cannot load classes registry file

Question

I have Windows 8.1 (64Bit). After trying today to log in to my account (user account) I get immediately signed out without even being signing in. I restarted my PC but the problem is still there. I can log in to my Administrator Account without problems. My PC has one Administrator Account and one User Account.

In the Event Viewer I get the message:

Level: Error
Event ID: 1542
Source: User Profile Service
Windows cannot load classes registry file. The system cannot find the file specified.

---

Level: Warning
Event ID: 4006
Source: Winlogon
The Windows logon process has failed to spawn a user application. Apllication name: . Command line parameters: C:\Windows\system32\userinit.exe

I tried to restore to earlier date but there is no restore point created. On my laptop I can login in the User Account that is not working on my PC.

Anyone any ideas what I could do ?

Solution

I created a New Local User Account. Then I logged in my Admin Account and deleted the User Account I couldn't sign in anymore. Windows 8.1 asked me if I wanted to save all the files of the User Account, which I did. After that I logged in the new created local User Account and connected it with my Microsoft Account and moved the saved files.

If you have a restoration point I would use that. Otherwise I would create a new user profile and transfer the old profile's files to its profile folder by taking ownership of the old folder. I have only see the registry become corrupt when two things happen in all my years of using Windows, the first is when people use registry cleaners the second I when there is a underline system storage device problem.

No I do not use registry cleaners. Yesterday everything was fine, but today I get the above problem. I remember that instead of shutting down the PC I clicked on Hibernate, I realised that and turned PC on again just to shut it down. I unfortunately don't have a restore point. So I will try creating a new User Profile and copy the files. Can you explain this a bit further ?

You just create a new user so your not using the built-in Administrator account. In the future don't shutdown the computer without first taking it out of hibernation.

I took it out of hibernation and after that shut it down. It is the only think I can think of that caused the problem.

[Ramhound]

If you shut the computer down the correct way then that's not the reason the registry hive became corrupt. Its likely because of a HDD problem I would clone the current drive and replace it.

Possible failing disk drive. Backup now. Check your hard disk for smart errors.

@DavidPostill I think the NTUSER.DAT file is corrupted. The file is located in the User Folder of the User Account (disable Hide protected operating system files). But I am still working on it.
