I'm going to try to make this sound as less complicated as possible. I have a hp all-in-one pc that originally came with win 7 pro oa (according to my coa sticker located on the bottom of the computer). I am currently using win 7 home, and it is giving me some problems such as not loading my integrated webcam and keyboard drivers. When I go to device manager, I can see the drivers, but the software is nowhere to be found on my computer. I am also getting "windows 7 not genuine errors" and a black screen b/c my product key is not valid with win 7 home. I guess my question is, is there any place I can get a valid and real copy of win 7 pro oa (x16-96076) for free and redo my computer using my product key that I already have?
