Plenty of places to get Iso's of windows and if it is a OEM then it is not illegal as long as it is the same OEM as your computer have and you have the number.
I downloaded a OEM from Torrent, which is a bit risky, but it was not cracked, just a OEM and if the number did not match on the computer it would not have worked. I tried it on another computer and it came up with not genuine windows logo yet it worked fine on the machine I got it for.
I would have preferred to get the ISO's from a safer place, but only until Batboy posted his link did I know where to get them from.
i doubt MS cares where people get a OEM or a reatil version from as long as said person have a legal licence.
You are just being a pain in the backside as normal
