Why Choose a Retail Key Instead of an OEM Key?
A Windows 11 Pro retail license offers more flexibility than an OEM license. OEM licenses are normally associated with the first computer or motherboard on which they are activated. A retail license can generally be moved to a replacement computer when it is no longer being used on the previous device.
Only one computer may remain activated with the key at a time. A motherboard replacement or transfer to a different PC may require you to enter the product key again or use Microsoft’s Activation Troubleshooter.
If you plan to replace major components, follow our guide explaining how to reactivate Windows 11 after a hardware upgrade. Transfer and reactivation remain subject to Microsoft’s licensing and activation rules.
Upgrade Windows 11 Home to Pro Without Reinstalling
You can use this Windows 11 Pro key to upgrade an activated Windows 11 Home computer to the Pro edition. In most cases, the edition upgrade keeps your installed applications, personal files and existing settings.
- Install all available Windows updates and restart the computer.
- Open Settings.
- Select System and then Activation.
- Next to Change product key, select Change.
- Enter the supplied 25-character Windows 11 Pro key.
- Follow the prompts and restart the computer if requested.
We recommend backing up important files before making any operating-system change. If Windows displays error 0xC004F050, follow the dedicated Windows 11 Home to Pro upgrade troubleshooting guide.
How to Activate Windows 11 Pro
If Windows 11 Pro is already installed:
- Connect the computer to the internet.
- Open Settings, System, Activation.
- Select Change product key.
- Enter your 25-character product key.
- Select Next and then Activate.
After activation, the Activation page should report that Windows is activated. Microsoft provides additional instructions in its official Windows activation guide.
If Windows is not installed yet, download the installation files from the official Microsoft Windows 11 download page. The Windows 11 ISO is multi-edition. The product key determines which eligible edition is activated.
Windows 11 Pro Features
Windows 11 Pro includes additional security, virtualization and device-management tools that are not fully available in the Home edition.
- BitLocker: Encrypt compatible drives to help protect sensitive data.
- Remote Desktop: Host a Remote Desktop session and access your PC remotely.
- Hyper-V: Create and operate compatible virtual machines.
- Windows Sandbox: Run untrusted applications in an isolated temporary environment.
- Group Policy: Manage advanced Windows and user settings.
- Domain support: Connect compatible devices to a business domain.
- Microsoft Entra ID: Connect supported work or school environments.
Some Windows 11 features require specific hardware. Before purchasing, check Microsoft’s current Windows 11 system requirements, including the supported 64-bit processor, TPM 2.0, UEFI Secure Boot, memory and storage requirements.
Instant Digital Delivery
There is no physical shipment or delivery charge. After your payment is successfully completed, the product key is displayed on the order-confirmation page and sent to the email address entered during checkout.
If the message does not appear in your inbox, check your spam or junk folder and confirm that the email address entered during checkout is correct.
Activation Support and Purchase Protection
If activation does not work as expected, confirm that Windows 11 Pro is installed, not Windows 11 Home, Enterprise, Education, Pro N or Pro for Workstations. Also check your internet connection, system date and time, and make sure the key is not active on another computer.
If the problem continues, contact SftKey support with your order number and a screenshot of the complete activation message. Eligible faulty-key cases are covered by SftKey’s replacement and refund policy. If a working replacement cannot be provided for an eligible defective key, the policy provides for a refund.
Frequently Asked Questions
Is this a retail or OEM Windows 11 Pro key?
This product is sold as a Windows 11 Pro retail key. It is not an OEM, KMS or volume-activation license.
How many computers can I activate?
One product key activates one PC at a time. You need a separate Windows 11 Pro key for every additional computer you want to keep activated.
Can I transfer the license to another computer?
A retail license can generally be transferred to a replacement computer after it is removed from the previous device. Significant hardware changes may require reactivation, and all transfers remain subject to Microsoft’s activation rules.
Can I upgrade Windows 11 Home to Pro with this key?
Yes. Enter the product key through Settings, System, Activation. Windows should perform an edition upgrade while retaining your applications, files and settings.
Does this key activate Windows 11 Pro N?
No. Windows 11 Pro and Windows 11 Pro N are different editions. A standard Pro key will not directly activate an installed Pro N edition. If Pro N is currently installed, follow the guide to change Windows 11 Pro N to Windows 11 Pro before activation.
Can I reinstall Windows on the same computer?
You can normally reactivate the same Windows 11 Pro edition on the same computer after reinstalling it. Keep your product key in a secure place and link the activated device to your Microsoft account to make future reactivation easier.
When will I receive my Windows 11 Pro product key?
The key is delivered instantly after successful payment. It appears on the order confirmation page and is also sent by email.
Does the purchase include Windows installation files?
The purchase includes the activation key only. Windows installation files are available directly from Microsoft at no additional charge.
What happens if the product key does not activate?
Contact our support with your order information and the complete activation error. The support team will verify the key, help troubleshoot the issue and provide an eligible replacement or refund according to the published policy.

I bought it on 7/30/2026 and it’s been amazing. Paying with PayPal gave me a lot more peace of mind, Thanks!
Alex –
Ngl, I was pretty skeptical about spending $29 on a Windows key because there are so many sketchy sites out there. Took the chance anyway, and it turned out to be 100% legit. The key was delivered in under a minute, activated without any issues, and the whole process was way smoother than I expected.

Such a good deal and the activation was super easy! I’ve never had any issues with stuff from this seller.

This was my first time trying them out, and the whole process was super fast. I normally get my license keys from Newegg since that’s where I buy most of my PC parts. A friend of mine in California who owns a computer store recommended these guys and said he uses them all the time for his IT business. I figured I’d give them a shot, and honestly everything went smoothly, the key arrived right away and activated online with no problems at all.

Everything worked flawlessly on my setup here in the US. I first tried reusing an old key I had, but it seems those aren’t accepted anymore since Microsoft changed their activation policy. So I went ahead and bought one from sftkey, paid with PayPal, and the process was super quick, I got the key instantly on screen and in my email.Really happy with it, thanks a bunch!

I recently upgraded my PC, but it didn’t reactivate automatically and none of the online tutorials helped. I even wasted time emailing Microsoft. Eventually, I tried a license key from this website, and it activated instantly. So far, everything is working perfectly.

I already had windows 11 installed on my PC but it wasn’t activated. I Read on a reddit post that this was the best site to use and after risking it and buying this windows 11 pro key, im very glad i did. I entered the code into my computer and it straight away upgraded me to pro. Took no more than 1 minute to receive my code and 5 mins for my PC to upgrade. 10/10 recommend to anyone sceptical and trying g to activate their windows for cheap!!!
KM –
I did a lot of research into product keys and settled on this website in the end. The product key worked, was the correct one (retail), and was delivered instantly. I did not want to risk my card info so it’s nice that they offer Paypal.
It’s your choice to risk it or not, but from a real person— mine worked!
Velimir Valjan –

Nicholas Marcum –
Worked well for me. Something to note is that if you have bitlocker enabled on windows 11 home that will prevent you from upgrading to windows 11 pro. To disable bitlocker, run command prompt as an administrator and run manage-bde -off DriveName
Stephen Gilmartin –
Worked perfectly for me in the Eu. Paypal payment, followed by display of the key, and the key activated immediately when inputted.
S.T. Oner –
I needed Win 11 Pro to use on my Parallels program on my Mac. I was also very skeptical of this outfit. Lots of scams these days on the Internet. You never know what to believe or who to trust. My key was delivered instantly and it activated perfectly! I am very happy and pleased. This company is legit. Thank you for saving me a ton of money!
Andrew Barker –
Always skeptical, I figured the price was cheap enough to give it a try… Plus with PayPal, I felt my purchase was a little more protecte. Got my key as soon as my receipt popped up on my screen. A quick copy/paste and I was on my way to rolling up from Home to Pro with seamless activation. Definitely recommend!
Alexis –

Was not sure if it was legit, but it worked! Activated like it should.
Thank you! Best price I’ve found for Windows 11 Pro anywhere.
Charles Simard –
Absolute 5/5 for these guys!
I actually just went in and it was unfortunately out of stock. Live chatted with their customer support, I asked them if it was going to go back in stock soon. The agent told me to wait a bit, 2 minutes later they had already replenished their product keys and I was able to purchase one.
You pay through Paypal which is excellent and you get your product key by email instantly. Activation worked perfectly.
Got the product for 35$ CA ($24.99 US) which is very cheap!
100% recommend.

I had my reservations about buying a win11 pro license, but after a couple of months of constantly checking for deals, I’ve decided to pull the trigger on this one.
And I have no regrets. When I confirmed the purchase on paypal, I have received the email with the product key included. Very happy with the purchase.
