Now you can wait for webpage displaying compatibility issues. I use Win 7 x64, and change to Windows 8.1. No matter what OS you are using. You can change your OS "Windows NT x.x"
Windows NT 5.1 = XP
Windows NT 6.0 = Vista
Windows NT 6.1 = 7
Windows NT 6.2 = 8
Windows NT 6.3 = 8.1
But change whole user agent string
