boy, can I relate to thatI've watched other keyboarders in action and I have to admit that I was impressed. As for me, I'm all thumbs and my memory chip is fried, so I remain a mouser.
So, if you want an operating system with a Start Menu, then stick with Windows 7 or if you want a Start Screen, then it's Windows 8/8.1.
So why bring out Windows 10. Is it to be the best of Windows 7 & 8 in one operating system. That being the case, then at least Windows 10 Start Menu should be at least as good as Windows 7 which it isn't.
Personally, Windows 8.1 with Start8 provides me with just that. A Start Menu just like Windows 7 & at the touch of button, straight into a Start Screen & back.
