Windows 10 Professional (32/64 Bit) 1 PC

les aseguro que no se van a arrepentir con su compra.

Rapide , Efficace et moins cher qu'ailleurs ^^

Tutto ok come sempre

I was really skeptical, but thanks to the positive reviews, I gave it a shot. It worked like a charm! Don't hesitate, and smash the 'Add to Cart' button!

. Everything arrived in minutes and I always got EXACTLY what I ordered. And they let you pay by SMS, which is brilliant!

Unkomplizierter Aufbau der Website und schnelle Übersendung zu ansprechenden Preisen。

Cool

I purchased Windows 10 pro key. I got support very quickly to fix the problem while installing while activating the key.

I do not usually write reviews and I have to say that I was pretty skeptical at first but I got my key in like 5 minutes and was able to activate windows successfully.

Semplicemente fantastici
Consigliati

simple, rapide, efficace :)

Obviously skeptical of this at first but the reviews are all 5 stars and I just did it myself, so yeah, no worries and it works.

Merci beaucoup

Schnell und unkompliziert wie immer.

Trustworthy & great price!

Great prices and super easy to use

The service of keysoff is amazing and i save alot of money using their service. Literally hundreds of euros were saved here already
And the customer service is verry good as well

Seriously, that was the easiest experience on God's green earth:

Step 1: Purchased the license.
Step 2: Checked email for confirmation of purchase. Received - from "Service Wintopay".
Step 3: Wait literally two minutes...
Step 4: Checked email for Windows 10 Professional key. Receivbed - from "Sales - Keysoff.com".

Have fun saving over $100 on a Windows Key! (I'm never going retail AGAIN!)

Simple, rapide, efficace, merci

A great product at the best market price.

Schnell und unkompliziert, wie immer. Jederzeit wieder

parfait

Excellent experience, as always.

Quick delivery, everything went fine

Rapide et code fonctiinnel

worked like a charm

Parfait a recommander

I was skeptical indeed like the rest. I to upgraded the mobo and needed a 64 Bit key within 5 minutes I had a new key Emailed.
-Thank you.

It is way cheaper than ANY other site (G2A, G2Deal, kinguin, etc. ) and IT TOTALLY WORKS! I've been using it for a couple months now and have had ABSOLUTELY NO PROBLEMS! The instructions on how to use it (it had instructions for how to upgrade and how to license a fresh install) were also thorough and clear. I came here from an article on licensing your windows 10 installation for cheap and I am not disappointed.

I was being skeptical at first but I was very impressed with the quick service and the value for money. Thanks, and you just found a constant customer.

Same as other reviewers, painless experience

I had Windows 7 upgraded for free to the Windows 10 Home and eventually wanted the Pro version. bought an Upgrade key then built a new PC but used my original install which started throwing up Hardware change errors. Spent a bit of time hunting and came across this from Tomshardware, bought a copy and now just 7 minutes after purchase its activated again.. Definitely going to buy more for a couple more PC builds i have going on.

Found this via the tomshardware's April '21 article. I was skeptical but it worked, I got the key via e-mail 5 minutes later, plugged it in and I'm good to go. As a heads up, it is an OEM license (so no transferring it to another motherboard).

I got scammed by g2a and came here after being recommended by wccfttech and I'm not disappointed with my purchase I'm going to buy at least 2 more licenses

Saw the price and pulled the trigger right away. Wasn't dissapointed!

Too good to be true.BUT IT IS. So nice Ima buy it twice

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
