KMS: recycle after computer removed RRS feed

  • Question

  • Hello.

     

    In our company, there is a KMS for windows 7 activation.

    Some of activated computers were lost or broken and will never be used again.

    How long will the count reset for those licenses?

     

    Thanks a lot.

  • Activation Count Cache

    To track the activation threshold, the KMS host keeps a record of the KMS client computers that request activation. The KMS host gives each KMS client computer a client machine identification (CMID) designation, and the KMS host saves each CMID in a table. Each activation request remains in the table for 30 days. When a client computer renews its activation, the cached CMID is removed from the table, a new record is created, and the 30-day period begins again. If a KMS client computer does not renew its activation within 30 days, the KMS host removes the corresponding CMID from the table and reduces the activation count by one.
