Frequently Asked Questions

How does this compare to the 500 PC tier?

The 400 PC pack is our large-enterprise tier for organizations and resellers deploying across several hundred machines. If your rollout is closer to 500 devices, our 500 PC tier gives you a bit more headroom per key.

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.
