Microsoft Windows 10 Pro – Retail key phone activation (1 PC)

Windows 10 Pro as a Retail licence for 1 PC, with phone activation. All the system's professional features are present; only the activation procedure differs from that of a standard online key. This route is officially provided by Microsoft, but it takes about ten minutes longer: we prefer to tell you before purchase.

The features of the Pro edition

• BitLocker — full disk encryption against data theft.
• Incoming Remote Desktop — take control of the machine from another device.
• Hyper-V and Windows Sandbox — native virtualisation and isolated test environment.
• Join a domain or Microsoft Entra ID — integration into a company's IT fleet.
• Group Policy and Windows Update for Business — control of configuration and updates.
• Microsoft Defender and Windows Hello — security and biometric authentication included.

Phone activation: the procedure

You receive the key by e-mail within 24 hours at most. Enter it in Settings › Activation; when online activation does not succeed, Windows offers Activate by phone and displays an installation ID. You dictate it to Microsoft's automated voice server, which returns a confirmation ID for you to copy back into the window. Have a phone and about ten minutes ready. Our support in French can guide you step by step.

When to choose it

This key is for users who accept this step in return for a lower price, or who install Windows on a machine with restricted network access. For immediate online activation, choose a standard Retail key.
