Configuring the Agent as a Windows Service would make sure that it starts up along with the operating system and is managed by the OS' own service management framework keeping it running.
In version 10.x, you could install Insight Agent as a Windows service by running
StartActionalAgentSvc.cmd but in later versions[Insight 2021], you can run
Launcher.exe -i Launcher.conf as the
StartActionalAgentSvc.cmd is not available anymore.
