Windows 10: start button,taskbar,settings and any deafult apps are not working

From past few days i can't open my start button,taskbar,settings and any deafult apps. whenever i try to open them it says " this file does not have an app associated with it for performing this action.Please install an app or, if one is already installed, create an association in the default apps settings page" . what should i do now?Please tell me any way without using start button,taskbar,settings.

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 ?

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
