Manually renew Microsoft Office KMS license for free

Manually renew Microsoft Office KMS license for free – By default, the validity period of the KMS license is only 180 days, and it will be renewed every 7 days from the date of activation. However, in some cases, this process may get stuck.

Here are some reasons for this problem:

  • When invoking the license update process, your PC is not connected to the Internet or the connection is unstable.
  • You are using a third-party firewall, so the connection to the KMS server was refused.
  • You are using a different version of Office on your PC. Retail version and batch version on the same PC?

If the Windows computer cannot re-establish communication with KMS after 180 days, the computer will lose its license. It will start a 30-day grace period and notify users of this change. If the computer is not activated for KMS after the 30-day grace period expires, it will enter reduced functionality mode until it can connect to its KMS.


  • Make sure your PC is always connected and the internet connection is stable.
  • If you use another firewall, please open port 1688.
  • Please do not use Office Retail and Volume on the same Windows.
