Start Button and taskbar not working


I did as suggested but didn't get to Troubleshoot or Reset computer. When it started back up with taskbar was complete and start button working. Everything seems ok, but slower. So thanks for that. Can you tell me about creating restore point manually and creating system image backup ?

Hello, there are so many threads on this topic, which can readily be found using the white search box at the top.

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
