Okay, I have created some services in Windows 7 through NNSM (Non-Sucking Service Manager) but now I don't know their service names anymore and I want to edit/remove them.
How can I find a list of the services installed through NSSM?
Every service added through NSSM, points to nssm.exe in the "Path to executable". You can see this in the Services MMC snap-in by right-clicking a service and choosing "Properties".
Run the following in Powershell to get a list of all services with "nssm" in the PathName (Based off this answer: https://stackoverflow.com/a/24449854/7470843)
Get-WmiObject win32_service | ?{$_.PathName -like '*nssm*'} | select Name, DisplayName, State, PathName
