So my old motherboard broke, and was no longer under warranty. I have windows 7 oem version although the pc was running windows 10 from the free upgrade. So I got a new motherbaord. I tried contacting microsoft via their online chat and they would refuse to give me the new key and said I had to contact the oem. The computer was custom built so it wasnt from like hp or dell. I bought all the parts and then sent them to a pc shop where they downloaded windows for me. I have seen other people being given new keys why wont they give me one?
