  1. Mark Damn

    After being fooled 3 times by people and company’s that seemed legit sold me product keys that were made up and I had my Own Lifetime purchaced key an COA that I’ve used for 4 years on 3 PC’s and 1 laptop and I upgraded to a SSD an Microsoft denied it ever existed or ad any record that really shocked me. Now I’m always very skeptical about buying anything from anyone even after I double checked the seller(s) and/or Companies, Corporations regardless who and how long they have been in business. I was so insecure about Winkey and so in doubt until I entered it without the media download tool just burnt the IOS and immediate validation and authentication no problems no questions asked. I couldn’t believe it went so smooth.
    Thank you Winkey, Mark Damn… Peace ✌
    To think I almost didn’t buy a Product Key from WinKey because it sounded to good to be true and it was everything they said it would be
