Microsoft Windows 11 Pro – OEM Key (1 PC)

Windows 11 Pro under an OEM licence for 1 PC. This is the edition designed for freelancers, SMEs and demanding users: it includes everything in the Home edition and adds encryption, virtualisation and administration tools. The OEM formula is the most economical option for a machine that will stay in place.

What the Pro edition adds

• BitLocker — full disk encryption, your data stays unreadable if the computer is stolen or lost.
• Remote Desktop (host) — the machine can receive a remote connection; the Home edition only allows you to initiate one.
• Hyper-V — native virtual machines, without third-party software.
• Windows Sandbox — a disposable sandbox for testing a suspicious file or program.
• Domain join or Microsoft Entra ID join — integration into a managed IT estate.
• Group Policy and Windows Update for Business — control over configuration and the update schedule.

OEM: what it means

The licence is permanently tied to the motherboard of the PC on which it is first activated. It is not transferable to another machine and replacing the motherboard may invalidate the activation. Reinstalling Windows on the same hardware, however, remains possible with the same key. For a licence you can move, choose a Retail version.

Hardware compatibility

Windows 11 requires a TPM 2.0 chip, Secure Boot and a compatible 64-bit processor. Check these three points with Microsoft's PC Health Check tool before ordering.

Activation

The product key arrives by email within 24 hours at most. Enter it in Settings › System › Activation › Change product key; validation is done online with Microsoft.
