anyone upgrade to Windows 10 yet? If so what are your first impressions? I like it. it's a lot more clean and simple than Windows 8 for sure. My only issue with it so far is that I can no longer utilize the two-finger touchpad scrolling on my laptop. kind of a big issue for me cause that was my primary navigating method. hope this issue isn't permanent and they fix it soon. anyone else have this problem with the touchpad scrolling? there a way to reactivate it?
