Windows 10: How to fix gray display with no search bar and icons at the bottom screen of ACER Laptop?

Please help me on how to fix this problem. My laptops screen do not show the real wallpaper but only display gray color as background. The window search bar is also missing and the other icons at the bottom like battery, time, and open applications. How to fix this

:)

 

Gray bar at bottom of each folder in large icons view

• What are the changes made or things you've done before the issue start? I ran hitmanpro.
• Do this gray bar displays on all folders and files in the File Explorer?
  The gray bar does display on all folders in the File Explorer but not individual files themselves. The gray bar only displays on all folders in view as Extra Large Icons, Large Icons, and Medium Icons. The gray bar does not show when view is either in Small
  Icons or List, or Details.
• Does the folders and files with the gray bar can still be accessed successfully?
  Yes all folders with the gray bar and the individual files in the folders can be accessed.

I am currently running System File Checker and will let you know if that works.

If if doesn't work then I'll run DISM or System Update Readiness tool as suggested.

Thank you so much.

*UPDATE*

The results of System File Checker says "Windows Resource Protection did not find any integrity violations."

Now I'll run DISM or System Update Readiness Tool as suggested.
