The RunAsSvc application application was designed to be a small tool that runs normal programs as services so that they are running in the background, even when no user is logged on.
Copy the file runassvc.exe to a suitable folder (e.g. "C:Program Files
unassvc"), then run the program. A Dialog will appear where you can select the EXE file to run and enter a name for the service to be created. Additionally, you can enter parameters to be passed to the program, the working directory for the program and a description for the service. After pressing OK, the service will be created and started.
