I have sort of the same issue. Windows 10, Start button! However I can right click on it and it gives me the maintenance menu, which is Good! But when I regular left click I SHOULD GET THE POPUP MENU!
However nothing happens. I checked all settings and went thru control panel for everything. Nothing helped. This one has me stumped!
I did try some of the suggestions listed here and none of them helped. However my Hard drive is new and checks out!
