The AppLife Update Windows Service allows limited users to securely apply updates that you publish under the security context of the local system account. This provides the ability to maintain your application on deployed clients without administrative support.
To use the AppLife Update Windows service for elevation, you must set the ElevationType property of the update controller AppLifeUpdateService. You must also deploy the service with your application and ensure proper registration. Deploying the service and registering your application to use it does require administrative privileges. Once deployed, your updates can be applied by limited users.
