Frequently Asked Questions

Can this key be used across multiple sites?

Yes — activations aren’t tied to a single location. As long as the total stays within 1000 devices, you can deploy across branch offices or client sites.

Do I need a KMS server for MAK keys?

No. MAK keys activate directly against Microsoft’s servers (or by phone for offline environments) — no internal KMS infrastructure needed.

Is this different from your other 1000-activation MAK listing?

Same underlying license and activation count. This listing is set up for large enterprise/multi-site rollouts; if you’re a smaller IT reseller or business, see our alternate 1000-activation listing — pick whichever fits your workflow.
