Frequently Asked Questions

How does this compare to the 2500 and 5000 PC tiers?

The 4000 PC tier sits between our 2500 and 5000 PC packs — pick it when your deployment is larger than 2500 devices but you don’t need the full 5000-activation pack.

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. Read our complete MAK key guide →
