How to Choose the Right Windows Key
Start with the version your hardware supports, then pick the edition. Windows 11 needs a 64-bit CPU on Microsoft's supported list, TPM 2.0 and Secure Boot. If your PC qualifies, Windows 11 is the right choice because it is the only consumer version still receiving security updates. Older PCs can still run Windows 10.

Product Key, Digital Licence and Activation
A product key is the 25-character code you enter in Windows. When Windows activates online, it records a digital licence for that PC, so reinstalling Windows on the same hardware reactivates automatically. Retail keys can be moved to a new PC; OEM keys stay with the first PC. All keys sold here activate online, with no phone call needed.
How Activation Works
- Create installation media with Microsoft's Media Creation Tool.
- Install Windows and enter the key from your order email.
- Connect to the internet; activation completes automatically.
- Confirm under Settings → System → Activation.

Here. Every Windows key we sell activates on Microsoft's servers and is backed by a 30-day money-back guarantee and lifetime replacement warranty.
Why are Windows keys cheaper here than at Microsoft?
We sell individual licence keys rather than boxed retail packs, which keeps prices lower. The software you install comes directly from Microsoft.
Do I need to buy a Windows key?

Can I transfer my Windows licence to a new computer?
Retail licences can be moved once removed from the old PC. OEM licences are tied to their original hardware.
What is the difference between a product key and a digital licence?
The product key is what you enter; the digital licence is the activation record Windows stores for your hardware after activation.
