Microsoft Windows 10 Pro – OEM Key (1 PC)

Windows 10 Pro as an OEM licence for 1 PC. The system is exactly identical to the Retail version: same features, same updates. Only the licence status changes — an OEM key attaches permanently to the hardware on which it is first activated. It is the most economical type of licence for equipping a machine intended to stay in place.

The features of the Pro edition

• BitLocker — full disk encryption, with recovery via a backup key.
• Remote Desktop as host — the machine can be controlled from another computer, which the Home edition does not allow.
• Hyper-V — native virtual machines, useful for testing software or running an older system.
• Windows Sandbox — a disposable sandbox to run a suspicious file without contaminating the machine.
• Domain or Microsoft Entra ID join — integration with a corporate directory.
• Local Group Policy and Windows Update for Business — control of the configuration and the patch schedule.
• Microsoft Defender, Windows Hello, Microsoft Store — all the features of the Home edition are included.

OEM: what it means in practice

The licence is tied to the motherboard of the PC. It is not transferable to another computer, and a motherboard change is liable to invalidate activation. Reinstalling Windows on the same hardware, on the other hand, poses no problem: the key remains valid. If you plan to migrate the licence one day, choose a Retail key instead.

Activation

The key arrives by e-mail within 24 hours at most. Enter it in Settings › Update & Security › Activation › Change product key. Validation is done online with Microsoft and takes a few seconds.
