Hi,
You could follow the following steps:
- Identify the activation ID by running this cmd:
Slmgr/dlv - Uninstall the KMS host key first by running CMD:
Slmgr/upk < activation ID> - Then, install the default kms key by running the following command:
slmgr /ipk <KMS Client Setup Key>
The default KMS client setup keys can be found here:
https://learn.microsoft.com/en-us/windows-server/get-started/kmsclientkeys - Delete the record from the DNS:
Open DNS console:
Expand _tcp node under the domain.com. There will be a record _VLMCS. Delete this record. - The KMS server is uninstalled.
Hope above information can help you.
