application is not referenced in any deployments, Configuration Manager will delete it
automatically after 60 days. However, this will not uninstall the application from any client
machines.
Uninstalling applications
If you do not require an application in your environment, you can deploy it with an uninstall
action. However, the uninstall deployment will fail if an existing install deployment for the
software affects the clients targeted with the uninstall action. Therefore, before deploying an
uninstall action, remove the install deployments for the application that you are uninstalling.
You need to remove the install deployments affecting only the clients on which you want
to uninstall the application. If the uninstall deployment is in a separate application from the
install deployment, you can retire it with the install deployment.
Uninstalling an application will not uninstall any dependent applications. The uninstall
action uninstalls all instances of the software regardless of whether the application was
installed by Configuration Manager, a manual process, or any other method. However, the
software to be uninstalled must be created as an application in Configuration Manager with
an appropriate uninstall command.
Thought experiment
End of application life cycle at Contoso
An application that is widely deployed on computers will no longer be needed in
several months. With this information in mind, you are considering what strate-
gies to pursue when the application is no longer required. As part of the planning
process, answer the following questions:
1. What is the difference between retiring an application and uninstalling an
application?
2. What might cause an uninstall deployment to fail?
Objective summary
■ Application management in Configuration Manager enables you to upgrade or replace
existing applications by using a supersedence relationship.
■ When you supersede an application, you can specify a new deployment type to
replace that of the superseded application.
■ You can configure whether to uninstall the superseded application.
■ When you supersede an application, the supersedence applies to all future deploy-
ments and Application Catalog requests.
