Microsoft Windows 11 Pro – Retail key phone activation (1 PC)

Windows 11 Pro as a Retail licence for 1 PC, with phone activation. You have the full set of the system's professional features; only the key validation goes through Microsoft's automated voice service rather than immediate online activation. Allow about ten extra minutes.

The features of the Pro edition

Phone activation in practice

The key reaches you by e-mail within 24 hours at most. After entering it in Settings › System › Activation, choose Activate by phone if online validation fails. Windows displays an installation ID to dictate to Microsoft's voice server, which returns a confirmation ID for you to copy back. Have a phone ready. Our support in French remains available to assist you.
