Windows 10 Professional (32/64 Bit) 1 PC

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!

I purchased Windows 10 Pro and managed to get a quick and reliable assist when I hit a bit of trouble. Bottom line, key works fine; service was very quick!

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.

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.

Super rapide et simple. Merci

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!!

It was a great experiece...it exceeded my expectations...thank you and keep it up.

Iam very happy. I installed my new software in few minutes after purchase from a Keysoff. Everyone was good. Discount prices are great! Thank you

Needed a license for the gaming PC I build my son for Christmas. Never bought a key before, but this worked perfectly! Thanks!!

Fast and reliable, activated my window in $7, thanks.

Great deal, everything works fine!

Very, very good prices and very good support in case of problems.
I had many concerns regarding this shop, because prices where very low, but I had an amazing experience.

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.

I was a little reluctant at first, and then the first key i received didn't work !
I contacted after sales service, and they answered with a new valid key really fast !
I recommend it !

Very good store, great service, quick response in post sale questions. Congratulations!!!

My first experience and it was Ok. No problem found, my product worked like a charm. Nothing bad to notice. I'll come back to buy more.

Honest people, Fast service and Fair pricing ... enjoyed every transaction.

Fast and reliable. I bought a Windows License and all the information in web page and email was pretty clear and easy to follow.

With 10 dollars a windows 10 pro license number ... what else? Excellent!

This is a good online store. I bought here a license for Windows 7 and Windows 10.

I purchase Windows 10 key from this site. I got support to fix the problem while installing while activating the key
