Re-enable Spotlight in Settings > Personalization > Lock screen by setting Background to Windows spotlight.

Performing steps 4 through 6 of How to Reset and Re-register Windows Spotlight in Windows 10 to reset the Lock Screen settings and delete downloaded assets (the OP also documents the manual method of doing this).
Disable Spotlight in Settings > Personalization > Lock screen, by setting Background to Picture or Slideshow.
So if you've recently changed the Windows Region and Spotlight stopped working then the following may fix the problem: After some brief research there appear to be certain regions where Spotlight is not supported such as Ukraine as documented here. However, after further testing I have discovered that it was in fact changing the Windows Region from United Kingdom to another European country which stopped Spotlight from working. I also tried all suggested solutions of the OP but unlike the OP what did work was trying Spotlight on the lock screen of a pre-existing but rarely used local account where it happened to be working perfectly from when I first logged in.īased on Reset Windows Spotlight I originally thought that this was due to registry settings in HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Lock Screen and suggested a solution based on replacing this registry path. I've been enjoying the Spotlight lock screen on Windows 10 and I had thought that a Windows update in November 2020 had caused Spotlight to stop updating its pictures as well as the Like what you see? feature to disappear from the lock screen.
