I have a new computer running Windows 8.1 Pro and I am considering downgrading to Windows Vista since I think it was the best designed Windows OS and I never got to try it. I had XP, Windows 7 and now 8 on this PC. Would my computer be compatible with Windows Vista or would I have issues if I tried downgrading. My laptop has a touchscreen so I am wondering if Vista is compatible with touchscreens. I also have a TB hard drive and a Bluetooth 4.0 radio built in which I don't know if vista will recognize. I am thinking of getting a Windows Vista Ultimate DVD and doing the downgrade. I know that Windows Vista was a bit slow when it was released but it should be fine on much newer and faster hardware I would assume.
