This topic is well-discussed in great length on the internet. My computer suddenly gave this warning after using the software for many years.
It was originally loaded with Windows 7 Ultimate. The previous owner decided he wanted the Vista upgrade (for free). I bought the unit used and wished to go back to Windows 7. I purchased a program re-install disk from eBay. It worked fine but needed a new product key, since the OEM key on the computer would not work. So I bought a “genuine” product key from eBay. It validated and again, has been working fine for several years.
Then two weeks ago, I got the fateful not genuine warning.So began my quest. I bought another complete disk set (from eBay) and was guaranteed that it was valid. I just needed the number, not the disk set, so I did not do a re-install, just tried to enter the new product key. My computer indicated it was not genuine. I contacted the seller and he indicated that it was indeed valid and provided a screen shot from the Microsoft website for validating software authenticity, https://www.microsoft.com/en-us/software-download/windows7 . I got an error code when I tried to validate it. (Message code 715-123130, Transaction ID 5ecb18e4-0962-434a-99ae-42e3e3d712ea ) I seem to recall some mention of Dell in the searches. I did not pursue them, but perhaps I should have, because that is where the issue lays. https://www.dell.com/support/article/us/en/04/sln104591/resolve-windows-7-not-genuine-issues?lang=en
I even had Microsoft remotely put a brand new image of Windows 7 Ultimate on my computer. When it was done, it asked for the product key. When I entered my new product key, which was verified by the technician, my computer still said that it was not genuine. I almost gave-up hope. I did not wish to reload Windows and wipe away all of my programs.
What happens if I do nothing? Well, apparently Windows just gets real annoying after 30 days, repeatedly prompting activation, as often as every hour, but the software still works.
While I was researching what would happen, I came across the Dell response again. https://www.dell.com/support/article/us/en/04/sln104591/resolve-windows-7-not-genuine-issues?lang=en . So I tried it. IT DID NOT WORK, THE FIRST TIME! But I tried it again and VIOLA! Genuine!!!
I hope this helps someone.
