Don't rush to me !
I came to Win8/8.1 directly from WinXp. One of my machine still has Xp and I am using it. Since Xp support is closed and I expect other developers will also move out, I installed Win7 on it (can not install Win8 as hardware is not enough).
Now when I first saw the desktop, it looked like Win8 desktop, with a round start button. I wanted to disable auto play and speed up keyboard. Just like habit of Win8, I tapped WinKey, typed 'auto play' and it showed me all control option for it 'in the start menu'.
Well I think I can seamlessly work on Win7 now, without need to learn something new. FARR is there for all other programs for me.
