Win 8 & Win 10 vsWin 7
I had the misfortune of needing to add a system variable to a Win 8 machine. I had previously made the same addition on a Win 7 box. The Win 7 box was a matter of a right click, a couple left clicks, and bang I was done. On the Win 8 machine it took me 15 minutes to just find the screen I needed to add the variable. If Win 10 is as "intuitive and easy to use" as Win 8, then help us all as our productivity will go thru the floor. Enterprises will need to spend beaucoup monies training just their IT staff let alone their line workers how to use Win 10. As I've said before, I couldn't get Win 10 Tech Preview off my computer fast enough when I tested build 9256 (or whatever the number was).
