I think you can try Re-register Spotlight Application method I have resolved this issue by following these steps.
1. Press Windows + S
2. Type “settings” in the dialogue box
3. Select Personalization
4. select Lock Screen
5. select “Picture” from the drop-down menu
6. Now, select Windows Spotlight
7. Exit the settings & restart your computer.
I hope these steps will work for you. If still, you face any type of issues then check this http://www.surfwindows.com/windows-spotlight-not-working/
