So i bought a pc that came with windows 8 and then I upgraded to windows 10 but my pc crashed and I went to my college informatic service so they could try to repair it. They did repair it but now im stuck with windows 7 and I dont have my windows product key. How can I go back to windows 10? btw windows updates dont work i get the error code 8024200D
