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.
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.
| Licensing option | Best for | Keys to manage | Infrastructure needed |
|---|---|---|---|
| Windows 11 Pro retail (1 PC) | Single PCs | One per PC | None |
| Windows 11 Pro 3-PC pack | 2–3 PCs | One order | None |
| Windows 11 Pro MAK (this product) | 50–500 PCs | One key | None (optional VAMT) |
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.
slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
slmgr /ato
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 is 64-bit only and has stricter hardware requirements than Windows 10. Check your PC with Microsoft's PC Health Check app, or compare against the official Windows 11 specifications.

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.

Reinstalling on the same, unchanged hardware usually reactivates without issue. Significant hardware changes or new devices may count as new activations.
