Frequently Asked Questions

Can I activate machines gradually over time?

Yes — you don’t need to activate all 20 PCs at once. Activate as machines come online, and the key tracks how many activations remain.

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 →
