Makes Windows 8 Almost bearable. But I do run into issues with Win 8 not liking drivers and some other stuff. It is also buggy with alot of the current software so I would not run it on my carpc. I actually loaded it first and without a full on touch device it is not worth the effort. Win 7 has been around a while and is well supported and for most anything posted on these forums there are drivers for Win7 but only MAYBE for Win8.
