Windows 11 Enterprise Key: Advanced Security for Managed PCs

Windows 11 Enterprise key: what the edition really changes

A Windows 11 Enterprise key unlocks everything in Windows 11 Pro plus a layer of security and management designed for managed fleets. The difference is not visible on the desktop: it lies in the kernel, in identity protection and in the control your IT team keeps over dozens or hundreds of machines. Genuine Windows 11 Enterprise licenses start at €13.99 per PC.

• Credential Guard: sign-in secrets are isolated in a virtualization-based container, enabled by default on compatible hardware, to block credential theft such as pass-the-hash attacks.
• Application control: AppLocker and App Control for Business policies, deployed through Group Policy or Intune, so that only approved software runs.
• Personal Data Encryption: protects the content of user folders on top of BitLocker, unlocked with Windows Hello for Business.
• Longer servicing: each annual Windows 11 release is supported for 36 months on Enterprise, compared with 24 months on Pro, which leaves a much calmer migration cycle.
• More headroom: up to 6 TB of addressable RAM, compared with 2 TB on Pro, useful for design workstations and heavily virtualized PCs.

Which Windows 11 Enterprise option fits your organization?

The word Enterprise covers several things: an edition of the operating system, but also per-user subscription plans and specialized variants. This table places each option before you decide.

To be honest, below about twenty PCs a Windows 11 Pro license already covers the essentials. Enterprise makes sense when you must lock down the list of allowed applications, prove a hardening level to a client or an auditor, and keep a whole fleet on a strictly identical configuration. For PCs that must never change, see our Windows 11 LTSC page, and for a detailed comparison of the two editions, read Windows 11 Enterprise vs Pro.

Deployment, activation and requirements

On a single PC the switch is immediate: open Settings > System > Activation > Change product key and enter your key. Windows applies the edition upgrade without reinstalling, keeps files, applications and profiles, then asks for a restart. Across a fleet, the key fits into your usual sequences: Microsoft Entra ID join, automatic Intune enrollment, Windows Autopilot for new machines, and Group Policy for environments still on Active Directory.

What to check before you migrate

Windows 11 requires a compatible 64-bit processor, 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot and, above all, an active TPM 2.0 chip. That last point still blocks many PCs built before 2018, so take an inventory before you order. Our Windows 11 installation guide walks through every step. If part of your fleet stays on Windows 10, remember that extended security updates only buy time: our page on Windows 10 end of support sets out the options.

Where our Enterprise licenses come from

Our licenses come from European companies that renewed, merged or downsized their IT. When a company replaces its machines, its perpetual licenses do not disappear: since the UsedSoft ruling of the Court of Justice of the European Union (case C-128/11), a perpetual software license sold in the EU can be resold, provided the first owner has uninstalled it for good and no longer uses it. The price gap comes from this second-hand market, not from any activation workaround.

Each key is checked before it is sent, activates on Microsoft’s servers and receives security updates like any license bought new. Nothing changes for your IT team: the same installation media, the same management tools, the same update channel.

What you get with your order

• Your key by email, usually a few minutes after payment, and within 48 business hours at most.
• A VAT invoice available in your customer account, ready for your accounting.
• Lifetime replacement of a faulty key: if a key is refused, we replace it.
• Email assistance 7 days a week, with a reply within 2 hours on average, through our support page.
• Secure payment by card, Apple Pay, Google Pay or Bancontact.

For several PCs, order one key per machine. If you are preparing a larger rollout, write to us before ordering: we will confirm which edition matches each group of machines.
