Perfect! review by W J on 1/18/2021
I'm like most here reading the reviews, wary of what seems too good to be true. But after giving it a shot, the key came in a few minutes with clear details on how to activate and voila, the key worked. I'm glad, thanks!

WOW! System and Wallet SAVER!!! review by Dent on 1/14/2021
I built a PC two years ago, I had to replace a bad MSI Motherboard on it. After I get the new rig running, Bill Gates says I needed to pay him AGAIN for the Windows 10 Pro I already paid him $125.00 for. What rip off artists Microsoft has become. I purchased the Product Key figuring at worst I'd be out a few dollars. Thirty seconds of spinning and my Windows 10 Pro is ACTIVE again! Thank you for fixing this so I did not have to pay twice for the same thing! Seriously, I owe you a debt of gratitude, thank you! I'd give you ten stars if I could.

That was easy review by Aaron on 1/13/2021
Sounded too god to be true, but I got my key in less than two minutes and it worked like it should. Hardest part was getting the iso from Microsoft.com on my thumb drive. The install.wim file is now larger than 4gb, so Fat32 will no longer work, but formatting as NTFS works. Took me way to long to figure that out.

Great, got code fast review by Randy on 12/4/2020
You know I was really skeptical to try this website out. I am used to G2A and Kinguin, but when I saw WCCFTech (Hardware news) post something about KeysOff, I thought I'll give it a shot. I bought Win 10 Pro for $7.45, so I had real low hopes for this actually working. I bought it, got a confirmation email from Keysoff.com and Service WinToPay. 4 minutes later, I receive an email with the product key. Activate it and works! Will def. recommend Keysoff to my friends!!

Super review by Paula on 11/25/2020
I couldn't believe the price on the software I received. I never thought I'd actually own it. The instructions in the emails were just great. I was able to do the download very soon after my purchase. The experience was just great all around.
