Microsoft Windows 11 Pro – Retail Key (1 PC)

Windows 11 Pro as a Retail licence for 1 PC. This is the most flexible formula of the Pro edition: all the professional features of the system and a licence that you can deactivate on one computer to reactivate on another. A one-off purchase, with no subscription.

What the Pro edition adds

• BitLocker and BitLocker To Go — encryption of the system disk and of removable media.
• Remote Desktop (host) — the machine accepts incoming connections, for remote working or maintenance.
• Hyper-V — built-in virtualisation to create and run virtual machines.
• Windows Sandbox — an isolated, disposable environment, wiped at each closing.
• Active Directory domain or Microsoft Entra ID join — the machine joins the organisation's directory.
• Local Group Policy Editor — fine-grained security and configuration settings.
• Windows Update for Business — deferral and scheduling of updates.
• Extended memory support — up to 2 TB of RAM, versus 128 GB in the Home edition.

Retail: a transferable licence

Unlike an OEM key permanently tied to its motherboard, a Retail key follows you from one machine to another. It is the sensible choice if you renew your hardware regularly or upgrade your configuration.

Hardware compatibility

Windows 11 requires a TPM 2.0 chip, Secure Boot and a compatible 64-bit processor. Check this with the PC Health Check tool before purchase: it is the leading cause of installation failure.

Activation

The activation key reaches you by e-mail within 24 hours at most. Enter it in Settings › System › Activation › Change product key, then link the licence to your Microsoft account to make future reactivations easier.

System requirements

• Compatible 64-bit processor, 1 GHz, 2 or more cores
• 4 GB of RAM, 8 GB recommended
• 64 GB of storage space
• UEFI with Secure Boot and TPM 2.0
• DirectX 12 graphics card, WDDM 2.0 driver, 9" 720p display
