How to repair Windows 10?

I am working on a computer that has Windows 10 installed.  The taskbar is missing Microsoft edge and the icon for the windows store.  Also the start button only works if you do a right click and then choose an option in black and white.  The start menu I had when I first installed windows 10 does not come up when I do a left click on the windows flag...the start button.  What might have caused this and how to I solve this problem?  The icons on the desktop all work...and I have set chrome as my default browser as a result of this problem.  Do you think it might be as a result of a windows update that has gone awry?  If not what has happened?
thanks,

A good repair tool for Windows 8, 8.1 and 10 is DISM (Restore Health). Try SFC and then DISM.

System File Checker:

Open cmd.exe with Run as Administrator and run SFC /SCANNOW.
Allow to complete, restart or, preferably, shut down the computer and then start up again.
Test to see if the problem has been corrected.

DISM:

Open cmd.exe with Run as Administrator.
DISM.exe /Online /Cleanup-Image /Scanhealth (takes 15 - 20 minutes).
DISM.exe /Online /Cleanup-Image /Restorehealth (takes 15 - 20 minutes).
Restart the computer and test.

I will do the backup of data for sure.  The PC was upgraded to windows 10.  Therefore, if I can go back to the previous OS version, which was windows 7, and then do a fresh update install to windows 10 and then restore the backup of data, how long approximately will this take?  I realize it depends on the specs of the computer...it is a fairly fast computer...an i7 intel processor.  My guess is about 3 hours...what do you think?
thanks,

Going back and forth? Why? Just do an inplace upgrade by starting windows 10 setup again on your current windows 10. It will repair things and usually correct errors like this.
