Windows 7 not genuine. Different computer so no error code yet.
Hi, just recently got asked to fix a laptop that has an error of windows 7 home premium not being genuine. However through some attempts and google-fu I can't find a way around it. No original CD-key nor installation discs. Also tried entering a different code so after I found out how to check the product key it displays the newer one. Any other way to find the old one?
