Microsoft original
The Software Protection Service reported that the computer could not be activated. The count reported by your Key Management Service (KMS) is insufficient.

What this means

The KMS host has not yet reached the minimum number of clients required before it starts activating, so it is not answering requests yet. This is how volume licensing works, not a malfunction.

Common causes

  • Not enough devices in the organization have requested activation to reach the threshold.
  • The host was just deployed and has not accumulated enough requests.
Do this first

Check whether enough devices in the organization have already requested activation from this host.

What to do next

  1. 1Wait for more devices to request activation, or ask IT to review the licensing method.
  2. 2Do not repeat the request just to raise the count.
Continue diagnosis from this code

Take what you know into the KMS diagnosis. It will ask a few more questions to narrow this down.
