When you use the application under subscription, Kaspersky Endpoint Security automatically contacts the activation server at specific intervals until your subscription expires.
If you use the application under unlimited subscription, Kaspersky Endpoint Security automatically checks the activation server for renewed keys in background mode. If a key is available on the activation server, the application adds it by replacing the previous key. In this way, unlimited subscription for Kaspersky Endpoint Security is renewed without user involvement.
If you are using the application under a limited subscription, on the expiration date of the subscription (or on the expiration date of the subscription renewal grace period), Kaspersky Endpoint Security notifies you about this and stops attempting to renew the subscription automatically. In this case, Kaspersky Endpoint Security behaves in the same way as it does when a commercial license for the application expires: the application operates without updates and the Kaspersky Security Network is unavailable.
You can renew subscription on the website of the service provider.
You can update subscription status manually in the Licensing window. This may be required if the subscription has been renewed after the grace period and the application has not updated the subscription status automatically.
To visit the website of the service provider from the application interface:
