I had a problem activating Win11. After a few email exchanges, my problem was solved, helpful and prepared team. Thank you.

I bought a couple of products from this company for an extremley good price. Windows 11 pro and office LTSC.
The first key for windows didn't work, but they rapidly sent me another which did. And i had trouble installing Office. They were very helpful and the problem was my end, YOU MUST install as administrator, then i had no problems. For the price i paid for these products i would have to say that RoyalCDKeys after sales service is excellant. I would recommend.

Awesome! Big game changer for me for sure lol

Fast and reliable checkout. Product activation is a piece of cake. Thanks.

Bought over 100 keys for MS Office and Windows so far. Not 1 days trouble.

I pasted the link I paid for to activate YouTube premium - no YouTube premium.

Excelente respond y great attention and results

I bought a Windows license from RoyalCDKeys n 2022, and faced some issue while installing it in my new laptop in 2026. RoyalCDKeys was very prompt in helping me, exceeded my expectations, and resolved my issue in the best possible way I could have imagined.

I am so happy I chose it for my purchase.

Beware, criminals are selling. There is a high chance that the code you are getting will not work and then you will have to chase them to get your money back. It is highly recommended to stay away.

Quick and efficient but had to follow-up with support to get the download link.

Fast delivery of product; all working 100%

Best prices, fast delivery. Top 5 stars.

Dear RoyalCDKeys Support Team,

Hello,

I recently purchased a Windows 11 Pro product key from your store (Order #1039793). However, I am unable to activate Windows using the provided key.

The system shows the following error:“This product key has already been used on another device” (Error Code: 0xC004C008).

I have only used this key on one device, and it has never been activated successfully. Based on this issue, it appears that the key may already be in use or invalid.

Could you please assist me by providing a replacement product key or resolving this issue?

For your reference, here are the details:

Product: Windows 11 Pro

Product Key: NW8GC-42BHH-GC7TK-M32TW-DGPKG

Order Number: #1039793

Please let me know if you need any additional information.

Thank you for your support.

Been using them for years always been good service. The latest win 10 key i got failed so I contacted support with a pic and explained what I did within an hour or so they had responded and after a few questions they had a new key that worked right away. You cant ask for better service. This is the first time I have ever had to contact them and they did great.

after some issues with the initial key the support solved my issue. They needed almost a week, but the price is a bargain.

ADVICE: Don't use the key durng the windows installation process, use it after choosing the desired version of the OS and after having completed the installation procedure.

First time when I bought the key it doesnt work, but after contact with support I received the new key and it totally works.

Good expérience. Had a bad key and helped me recover a new working one. No issues now

I can't recommend RoyalCDKeys enough. I had an issue ( my issue 😕) with a code and they were super helpful. They were constantly in touch with me and helped me every step of the way to get it sorted. Don't hesitate to use RoyalCDKeys because you will definitely grab a bargain and the service is Spot on. Highly recommend ⭐⭐⭐⭐⭐
