Microsoft Windows 11 Pro MAK (Multiple Activation Key) is a volume licence key that activates Windows 11 Pro on a fixed number of devices — from 50 up to 500 — using a single key. It's built for businesses, schools and IT teams deploying Pro across many PCs without buying and tracking individual retail keys.
What Is a Windows 11 Pro MAK Key?
A MAK is a volume licensing key that Microsoft counts against an activation limit. Each PC activates once directly with Microsoft's servers, and every successful activation uses one slot until the limit you purchased is reached. Unlike KMS, MAK needs no on-premises activation server, which makes it the simplest volume option for small and mid-sized fleets.
Available Activation Limits
Choose the pack that matches your fleet: 50, 100, 150, 200 or 500 activations. Size it for your current device count plus room for replacements and reimaging, since activations on new hardware count against the limit.
Windows 11 Pro Features on Every Device
-
BitLocker encryption and Windows Update for Business for managed, secure endpoints.
-
Active Directory and Microsoft Entra ID join with full Group Policy support.
-
Remote Desktop host, Hyper-V and Windows Sandbox.
- Compatible with Intune, Configuration Manager and standard imaging workflows.
How to Activate a MAK Key
- Install Windows 11 Pro on each device (download from Microsoft's Windows 11 page or use your existing image).
- Open Command Prompt as administrator and install the key:
slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
- Activate online:
slmgr /ato
- Check status with
slmgr /dlv, which also shows remaining activations.
For larger rollouts, Microsoft's free Volume Activation Management Tool (VAMT) lets you install and activate the key across many PCs centrally. Each machine needs an internet connection to activate.

Windows 11 Pro MAK FAQ
Does MAK work on Windows 11 Home?
No. MAK keys activate Windows 11 Pro. Devices running Home must be switched to Pro, which the key itself can do via Settings → System → Activation → Change product key.
What happens when I reach the activation limit?
Further devices won't activate with that key. Contact us to add capacity with an additional pack.
Does reinstalling Windows use another activation?
Reinstalling on the same, unchanged hardware usually reactivates without issue. Significant hardware changes or new devices may count as new activations.
Is this a subscription?
No. It is a one-time purchase and every activated device keeps receiving Windows updates.
Can I get an invoice for my business?
Yes. Every order includes an invoice by email, which you can use for your records and asset management.
