Windows 11 Pro OEM

The business edition of Windows 11. Everything in Home, plus the management and security features you need once a machine has to join a company network or hold sensitive data.

OEM licence for one PC. This is a Windows 11 Pro OEM key: it activates one computer and then stays with that machine. Reinstalling Windows on the same PC is fine, but the key cannot be moved to a different computer. Ideal for a new build, a fresh install or upgrading the PC you already use.

What Pro adds over Home

• BitLocker drive encryption
• Join an Active Directory or Microsoft Entra domain
• Remote Desktop host: connect to this machine, not just from it
• Hyper-V virtualisation
• Group Policy and Windows Update for Business

System requirements

• 64-bit processor, 1 GHz or faster, 2 or more cores
• 4 GB RAM and 64 GB storage minimum
• UEFI with Secure Boot, and TPM 2.0

Running Windows Home?

You can still use this key. If your PC currently runs Windows 11 Home, our email includes step-by-step instructions to switch the edition to Pro first, using Microsoft's generic upgrade key, and then activate it with your Pro product key. No reinstall is needed and your files stay in place.
