COM+ System Application
The COMSystem Application Service is used for tracking and configuring COM+ components. COM+ can be used to develop enterprise-wide, mission-critical, distributed applications for Windows.
If the service is stopped, most COM+-based components will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start.COM+ System Application Service will be set to “Manual” by default on Windows server 2019. There is no need to start the service.
In short, this application manages the COM+ Event System. One of the support files you’ll probably never use but disabling it will result in higher warning notifications than leaving it enabled. When this service is disabled, Event Log entries are created to note that it is not active. Not dangerous, but annoying.
