Hi Daniel,

 

Thank you for posting your query in Microsoft Community.

 

I understand that you are unable to set a lock screen picture. I will be glad to assist you with this.

 

To assist you better, please answer the questions below:

1. Did you make any changes to the computer prior to the issue?

2. Is the issue specific to a particular picture?
3. Are you logged in as the administrator?

 

Meanwhile I would suggest you to try the methods below and check if it helps:

 

Method 1: Choose lock screen picture from photos app

1. Open the desired picture through photos app
2. Right click>set as>set as lock screen

 

 

Method 2: System File Checker(SFC) 

System File Checker scans all protected system files and replaces incorrect versions with correct Microsoft versions. When the scan is complete, the System File Checker tool indicates whether integrity violations were found. If integrity violations are found, the System File Checker tool lets you fix the integrity violations.

Follow these steps to SFC scan

1. Press the Windows key + X  and click/tap on Command Prompt (Admin).

2. In the elevated command prompt, type sfc /scannow and press Enter.

 

If this doesn't help, please proceed to the next method

 

Method 3: Create a new user account

I would suggest you to create a new user account and check if the issue persists.

Refer to the link below for steps to create a new user account.

Set up accounts

 

Do get back to us with the result. We will be glad to help if you need further assistance.

Hi Daniel,

We appreciate your time and effort for getting back to us.

I would suggest you to perform the System Restore and check if it helps.

Note: The system restore takes your PC back to an earlier point in time, called a system restore point. Restoring won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.

I would recommend you to refer to the section: Restore from a system restore point from the following Microsoft

article on Recovery options in Windows 10.

http://windows.microsoft.com/en-us/windows-10/windows-10-recovery-options

Kindly let us know if you need any further assistance with Windows. We are happy to assist you.

Thank you.

After much reading I managed to fix this problem.

I didn't have an image at the lock screen at startup. Whenever I tried to change the image to somethig of my preference it showed gray screen with endless loading.

Anyway, here is what I've done:

First I disabled apps that show on lockscreen:

Then I removed everything from [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Lock Screen] , or at least remove most things from it. (The reason is the key will be populated with info later)

Or you can use this reg key with minimal entries: https://app.box.com/s/zdqvhh2cnqqth0hifw3hnb4b3v3eu0hm

After that navigate to C:\ProgramData\Microsoft\Windows

There you will find SystemData folder.

You have to take ownership of that folder. Here is a tutorial how: LINK

After that you can either rename the folder to SystemData_bak or delete it (your choise).

Finally restart explorer. Open Task Manager, find Windows Explorer and click on Restart.

And voila I was able to change the lock screen image.

You can check the reg key is now populated and SystemData is recreated.
