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.
The one I am using may not be as good. I might try a different one. Thank you!!! Hate the Win8 feel and how sensitive it is!
