gray bar at top in Windows 10

I was stupid enough to upgrade to Windows 10...it MESSED everything up. Right now I have a large gray bar at the top of screen, under it I have 2 more large little gray bar....I only want one small search...2 inches wasted at the top.....also how do I
get back my yahoo home page? The top darker gray bar has an X to close it out..under it is a bar with arrows on the left and 3 dots on the right....under it is a bar that shows facebook and and M for gmail although I have a Facebook and Gmail short cut on
the bar on botton of page.

How do I get rid of the gray bar at the top of the screen over the search bar in Windows 10? How do I make both those bars more narrow, over an inch at the top is wasted?

 

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.
