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
"Mozilla/5.0 (compatible; Windows NT 6.0; U; WOW64; IA64; en) AppleWebKit/599.0+ (KHTML, like Gecko) Maxthon/4.4.0.4000 Chrome/34.0.1847.137 Safari/537.36 OPR/21.0.1432.67 QupZilla/1.6.6" or with any "large" others, will give you problems. above all U; |AppleWebKit/xxx.x+ |OPR/xx.xx.xx | QupZilla/x.x.x | Maxthon/x.x.x.xxxx]
My user agent string picture is attached. Never had problems
