Windows 10: I can't sign in. It's stuck at sign in screen

I can't log into Windows. When I click "sign in" it stays the same. Even I enter safe mode. It still wants me to sign in. But I can't sign in anyway.

:)

 

different lock screen and sign in screen?

Step 2b is labeled as Change the Login Screen Image, but the steps show you how to change the Lock Screen image. Step 2a is irrelevant. It only tells you how to change the desktop background.

What I want to do:
Set Spotlight as the LOCK Screen Image(s) - Done
Set the Win 10 Hero Image as the SIGN IN Screen Image - This is the one that shows after you click on the lock screen and you are able to type your password. If I uncheck "Show Lock Screen Image on Sign In Screen", it shows a solid blue background behind my Password box and user image. This is what I want to change to the Hero Image....

 

App Store sign-in error, 0xD000000D

Hi Suzanne,

There's a possibility that you are currently signed in on your computer using your local account. For us to sort this out, we suggest that you sign in with your Microsoft account instead. Follow these steps:

• Open Settings > Accounts > Your email and accounts.
• Select Sign in with a Microsoft account instead.
• Follow the on-screen instructions.

Once signed in with your Microsoft account on your computer, try signing into the Windows Store app.

Update us with the result.

Regards.

 

Sign-in Screen Disappears

Hi Ermie,

It is possible that the sign in screen disappears due to corrupted system files. To assist you better, we'd like to gather more information:

• Have you made any recent changes prior to this issue?
• Are you able to see the password box?
• Could you provide us a screenshot of the sign in screen on your end?
• What troubleshooting steps have you done so far?

We're looking forward to your response.
