cannot change lockscreen

Hi Thaker,

Thank you for your interest in Windows 10!

I would suggest you to try the following methods and check if you are able to change the lock screen.

Method 1:

Try to run a System File Checker (SFC) scan to check for any file corruption.
SFC scan will scan for corrupt system files on the computer and repair them.

• Press Windows key + X, click
  Command Prompt (Admin).
• In the Command Prompt, type the following command, and then press ENTER:
  
  sfc /scannow

If the issue still exists, try the next method.

Method 2:

You may check the same issue with the new user account.

Try these steps to create a new user account and check if it fixes the issue. Refer to the steps below to create a new User Account:

• Go to Settings.
• Choose Accounts and then select Other User Accounts towards the left.
• Select Add an Account.
• Enter a user name and hit Next.
• Click on Finish.
• Sign out from the current Account and Log into the new account.
• Check if issue persists.

Hope this information is helpful. Do let us know if you need any further assistance, we'll be glad to assist you.

 

Lock screen settings won't change, no error message.

Thank you for the detailed response zdzdz, I'm glad it worked for you.

I tried the steps you listed and it didn't fix it for me. It did remove all my existing lockscreen images, so now I just have a black screen as the lockscreen. I can't even change this black lockscreen back to the picture slideshow now. Gaaahh Windows.
