I currently have windows 7 professional installed, but below my pc, It says I'm supposed to have windows 7 home premium Oa, I went to fix this pc some months ago, and sometimes I get things saying my pc it's not verified, but I do have my key here.and when I put it on my "Windows activation" thing that happears sometimes it says my key won't work with this windows edition. Is it possible to download the home premium OA without the cd? And is that the problem? If you need more information please ask, it's urgent, thx.
