Start Button displaying but not working


The start button was working until there was a forced reboot (power failure). Then left click (normal click) over the start button does absolutely nothing. Right click brings up a menu but "programs" and also "settings" are missing and not included on this list. Search or Task View buttons do not work either with "normal" click. Does anyone have any suggestion or fixes?
Thank you in advance *Huh

Start Button Not Working?


What steps should be taken to diagnose a Windows 10 start button not working?

 

Start button not working and upgrade.

Thanks FreeBooter.
I ran the bat file from the Windows directory in Powershell, a few times but it didn't work.

Told myself that there were more issues with this PC than just the Start button not working. It's like all Microsoft software just does not work.
Tried to disable then remove many programs, then removed Avast, then thought I could get the Start button working by performing the update to 1909, (as there is a bit of commentary that this has cured the Start button problem in the past).
Spent hours unsuccessfully trying to get the 1909 update, to work.

Finally I did a RESET on the Laptop (saved my personal files) and this does actually get the Start button working again, and Microsoft programs working.

Then before installing other software such as Avast, Google Chrome, Waterfox, LibreOffice, Sony Handycam software, I attempted to do the update and it failed again.

Can you suggest a thread as to what I might need to get this 1909 update working.
Is it a good idea to re-install all my third party software before I attempt the update again?
