Using the graphical user interface, you can add and remove application license keys, and view information about the license under which the application is being used as well as the associated license key.
You can activate the application by adding an active license key.
Activation is the process of activating a license that allows you to use a fully functional version of the application until the license expires.
If you are using the application under a license that does not include the Kaspersky Endpoint Detection and Response Optimum functionality, then to activate this functionality, you need to add an additional Kaspersky Endpoint Detection and Response Optimum Add-on license key ("EDR Optimum key").
You can also add a reserve key to the application. The reserve key becomes active when the license associated with the active key expires or when the active key is deleted. Availability of a reserve key allows you to avoid application functionality limitation when your license expires.
A reserve license key can be added only after adding an active license key.
