Some operations like installing a service, changing the priority of a process or creating a temporary IP-route for improved WOL-functionality will not work without those rights.

These methods are available:

- None: no administrator operations can be executed (unless program already manually is started as admin)

- Run as admin: only available when starting automatically after login (configures scheduled task with highest privileges)

- Use Windows Service: this will install a Windows Service that handles the operations which need admin rights. This is the preferred method.

- Use dedicated elevated process: a second ColorControl-process will be spawned that is run as administrator.

The best and suggested method to provide this is via a Windows Service. Only when installing the service a User Account Control window may popup.";
