I downloaded from Pirate Bay MSDN images of Windows 7 Home Premium and Professional (32 and 64 bit) and I checked and it's OEM version. I checked SHA-1 of images on MSDN with mine and it's not same. Sizes is same (2.39 GB for 32-bit, 3.09 GB for 64-bit). My question is: Is my copies legal or illegal ?
