Unable to change lock screen background mode.

Hello, I am pretty good with computer but I have ran in to a problem I just can't fix. The operating system will not let me change the lock screen background mode from Windows Spotlight to something else. I have searched for an hour without any luck. My laptop has had a history of breaking down. The first time was hard drive failure and I have lost all my data. The second time I needed to repair was when the computer got so slow it was unusable and eventually got blue screens at boot And I needed to reinstall the operating system. When I try to go to edit the setting it is grayed out and on the top it says Some settings are managed by your organization" I am not apart of any organization and I am the only user on the computer with Administrator privileges. I would be very happy if you could help me with this, thanks in advance!

I have a very similar problem as this with my lockscreen which I've been trying to fix for about a week. I have seen that it seems many have similar problems so it may be a common windows error. For a while my lockscreen was the default red rock formation but only half of it showed as the bottom half was black. Now, when waking from sleep or restarting, My lock screen will be all black when I wake it up like it's trying to load a picture but cant. I can't click through to the sign in screen so I have to wait but it eventually just goes to the signin screen. Attempting to go to personalization>lockscreen grays settings out without going to the lockscreen option and then I just have to close settings. I tried Deleting all files in C:\Users\username\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\Loca lState\Assets and turned off sync for themes and windows settings and windows spotlight was working fine with new images last night and this morning but now it's back to the same thing. I get a security warning when selecting all files in the above folder and right clicking also.

Clicking personalization>lockscreen screenshot



Security warning in windows spotlight folder

Still can't change it to picture. It is still locked on windows spotlight

If i am not mistaken Lock screen is not that spotlight picture it is the one before it you can change not where you sign in.

Is your edition of Windows activated?

Yes it is activated

Have you applied any 'Telemetry Disabling' tweaks or software of any kind?

No I don't.

I have about the very same issue, as far as this " When I try to go to edit the setting it is grayed out and on the top it says Some settings are managed by your organization" I am not apart of any organization and I am the only user on the computer with Administrator privileges." At least for me..I don't use the lock screen at all..as I'm the only user of my pc, there's really no need to use it.
