I have a custom built PC running Win 7 Ultimate that is Non-Genuine. I have a number of Product Key codes from defunct PCs that also ran the same OS. All these keys fail the validation test. Now I also purchased a BRAND NEW OEM license
with an updated version of Win 7 U that also fails validation.
Is there a way to reuse a key of a computer that fire or other violent event put out of business? I cannot reinstall after formatting the hard disk (SSD) as I do not have access to the installation programs anymore
Thanks for any help
