Windows 10: I restarted my computer, now I am not allowed to sign in.

So this evening I decided to restart my personal windows 10 computer and upon restarting I cannot login. I try to enter my pin and it says "Your credentials could not be verified."Okay, no problem I thought. I hit "OK" and the next message reads, "something went wrong and your pin isn't available status: 0xc000006d, substarus: 0x0. Click to set up your pin again.So I click "Set up my pin" and it asks me to sign in to my Microsoft account which is bound by my phone number. I sign in to my Microsoft account with the correct password and I verify my identity through my phone number with a code.

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.

 

Sign-in method not allowed

Hi,

This issue may happen if you're signing in to a computer using non administrator ID.
In order for us to efficiently you, we just have few questions for you:

• Were there any changes made to your computer prior to the issue?
• Is your computer connected to a domain?
• Have you checked the Group Policy if the "Allow log on locally" was setup to allow users or domain users?

Regards.
