How to reset Windows Spotlight
If the Windows Spotlight feature is stuck on the same image, or it's not working at all, you can use the following steps to fix the issue:

1. Open Settings.
2. Click on Personalization.
3. Click on Lock screen.
4. Under "Background," make sure Windows Spotlight is NOT selected and change the option to Picture or Slideshow.

5. Use the Windows key + R keyboard shortcut to open the Run command.
6. Type the following path and click OK.

%USERPROFILE%/AppDataLocalPackagesMicrosoft.Windows.ContentDeliveryManager_cw5n1h2txyewyLocalStateAssets

7. Select all the files (Ctrl + A) and hit the Delete key to clear all old images (if applicable).

8. Use the Windows key + R keyboard shortcut to open the Run command again.
9. Type the following path to where the Windows Spotlight settings are stored and click OK.

%USERPROFILE%/AppDataLocalPackagesMicrosoft.Windows.ContentDeliveryManager_cw5n1h2txyewySettings

10. Right-click settings.dat and roaming.lock individually, then click Rename and name them settings.dat.bak and roaming.lock.bak.

11. Restart your computer.
12. Open Settings.
13. Click on Personalization.
14. Click on Lock screen.
15. Under "Background," make sure to enable Windows Spotlight.

Once you complete these steps, you can lock your PC (Windows key + L), and the Lock screen should show new Bing images.

If everything worked as expected, remember to go back to the Settings folders where Windows Spotlight stores the settings and delete the settings.dat.bak and roaming.lock.bak files.

Alternative method to fix Windows Spotlight
If the steps mentioned above didn't fix Windows Spotlight, you can try to reset the settings using the following steps:

1. Open Settings.
2. Click on Personalization.
3. Click on Lock screen.
4. Under "Background," make sure to enable Windows Spotlight. (If you don't enable the feature, you're likely to get an error while running the PowerShell command.)

5. Open Start.
6. Search for Windows PowerShell, right-click the result, and select Run as administrator.
7. Enter the following command and press Enter to reset the Windows Spotlight:
Get-AppxPackage -allusers *ContentDeliveryManager* | foreach {Add-AppxPackage "$($_.InstallLocation)appxmanifest.xml" -DisableDevelopmentMode -register }

8. Restart your computer.
After completing these steps, you should be able to lock your PC (Windows key + L), and the Lock screen should show new Bing images.

restarting now, will let you know if the first set worked.

those instructions are really simple.

2nd set just errored out saying it couldn't find the path and now I can't even get to the folders I visited in the first path, those are like gone even though all I did was delete files, not folders.

All in all ... fail for me.

But they might work for you. Worst case AFAIK is ... it doesn't fix it.

BTW easiest way to powershell (admin) is to *right* click the Start button. And when you're in there, right click at the prompt will paste whatever is in your clipboard.

For starters, getting to the Run window, following the detailed directions exactly (Windows + R), capital R got nothing. Innovating to use the lower case "r" got there.

I guess I'll call HP.

You could try a full-blown Windows repair. That would probably work.

E.g. if you engage caps lock to make r into R, it still works.

What doesn't work is Windows+Shift+r ... if they'd meant that three key combo, they'd have said that

I've had an awesome picture of the Hong Kong skyline at night (taken from Victoria Peak) as mine for years and years

only those characters ...

From Google got phone support. Got Virtual Agent, which didn't get the right problem, sent me to Phone Assistant, who issued a Ticket # and transferred me to Tech Support. This fellow fixed it, went through the steps to the "Run" window, changed the File Extension adding something to the DAT extension. Now the pics are back to rotating.

The phone # that worked for me: 425-635-2970
