Well i have a legit windows 8 pro upgrade key and i have a ISO for Windows 8 pro x64bit which is downloaded from MSDN my question is will i be able to do a clean install with the downloaded ISO and activate its successful using my upgrade key??
Yes and No, you can do a clean install, but you can't use the upgrade key until you again run Win8 setup to upgrade other the top of Win8! After it's done, enter your upgrade key and it should activate automatically.
sorry i did't get you..as i said i have a windows 8 ISO from msdn subscribers download...but i have a legitimate windows 8 pro key..so the thing is if i make a clean install using the ISO which i have downloaded and after installing using the upgrade key.....can i successfully activate the copy of my windows 8 pro ???
