What Is a Windows 11 Home OEM Key?

An OEM (Original Equipment Manufacturer) CD key is a genuine Microsoft activation key that permanently activates Windows 11 Home on one specific device. The licence is tied to the first machine it activates on and cannot be transferred to another PC. Used by PC manufacturers, system builders, and refurbishers worldwide, OEM keys activate identically to Retail keys through Microsoft's official servers — you get the complete Windows 11 Home experience at the most competitive price available.

Frequently Asked Questions

Is an OEM key a genuine Microsoft product?
Yes — completely genuine. OEM keys activate through Microsoft's official activation servers, and your PC will show "Windows is activated" in Settings after installation.

Can I use this key on a fresh Windows 11 install?
Yes. Enter it during the setup process when prompted for a product key, or enter it through Settings → Activation after installation.

What if my PC doesn't support Windows 11?
Windows 11 requires TPM 2.0 and Secure Boot. If your PC doesn't meet these requirements, we recommend our Windows 10 Home OEM key, which works on a much wider range of hardware.
