Yeah, so I bought windows 8's upgrade from Windows 7 and got the key for it, and then a couple of weeks ago I switched my Motherboard and now I can't activate my Windows 8 because "this key doesn't work please check the spelling and try again" ,but my Windows 8 is installed on this hard drive, the solution is to call Microsoft support, seriously? I have to call them every time I install a new computer hard drive?
