My system updated Windows 10 the other night. Since then, I cannot use Edge - when I place the cursor over the icon nothing happens, nor when I right-click over it - no menu pops up. Worse still, when I click on the windows icon in the bottom left corner of the screen, nothing happens, so I can't get into settings, apps etc. I have run the sfc/scan and no difference. Fortunately Chrome still works fine (so far!). I can't enter anything in the box "search the web and Windows", if I click on the little briefcase icon nothing happens, but Office 2010 works and I can access Office 365 through Chrome. Does anyone have any suggestions as to how to fix the problems? I am not a techie but reasonably savvy! Thanks in anticipation.
