There are a lot of benefits if you can make normal programs run like system services, for example: start a program when no user is logged in to the computer or is not under the specified account, make it run 24/7 without human intervention, make if work fine after logging out/logging in, run it quietly in the background, run it under a specified account, and more. To do this, in addition to using Application as Service, you can also try AppToService.
