You don't get a start 'button' but an app, lower left corner with mouse pointer, for a Start screen. Right click in that screen and all your 'all programs' are there. To search from that screen then it's right corner with the mouse pointer and you get , search, share, start, devices and settings. Simplicity itself. I can't fathom out why anybody would use a third party software just to get the 'start' button on the desktop that will only show what you get in the start screen anyway. You can also pin some apps to your desktop's taskbar. Control panel for instance. Win 8, for me, is the best yet from Microsoft though I had my doubts originally.
