I d/l a program so I would have the start button and the W7 feel. I sometimes hit the windows key and have to deal with it and keep getting it by accident. So, I restart and all is well. lol
You should have no need to restart. The “start button” programs I have used work without this and give a Windows 7 feel meaning>>>>>
You get back the start button and desktop and bypass the tiles which are for touch sensitive tablets (no mouse is used) and smart phones where tiles do make sense. But not on a laptop or desktop where a mouse is used.
