Troubleshoot Windows is not Activated

Troubleshoot Windows is not Activated

Normally, Azure Windows VMs automatically activates via the Azure KMS (Key Management Services). If you see a message that Windows is not activated, these warnings usually clear up with time or a restart of the VM.

Note: You should not see any impact to user functionality when an Azure VM displays this message.

You can attempt to force the activation with an slmgr -ato from a command prompt. If this command results in an error, the details may state that the Azure KMS service is unreachable. This would indicate the KMS service is unavailable and perhaps under maintenance. You should attempt the command again at a later time and it may resolve this issue.
