Once a new license key has been imported to existing On-Prem environment, you may notice a pop-up message in your GPMC console mentioning your old license key is getting expired soon.
One or more similar messages may appear in MMC/GPMC when editing a GPO.
As example, this can occur if you have two license GPOs in your domain.
For instance, two license GPOs are linked with the following expiration dates:
GPO 1: Expires March 1, 2023
GPO 2: Expires March 1, 2024

If you still get pop-up messages and the messages reference the registry, you should check under the following registry keys on your GPMC management station for any old information relating to the old license.
