Auto start: using shortcut

Use case: You would like to automatically run VSPE configuration when user logs in

VSPE can be started on Windows startup (after user has logged in) by putting shortcut to Autostart folder, as described below.

  • Create config file
  • Create VSPE shortcut which opens config file
  • Test shortcut
  • Put shortcut to 'shell:startup' folder

Below is a short video demonstrating how it can be done.

Auto start: as Windows Service

Please note that you cannot run VSPE and Service at the same time. In order to start VSPE, you will need to stop VSPE Service.

Start VSPE, pick "Helpers -> Set up as Windows Service", and then point to your VSPE config file. Follow the steps.


Run cmd.exe as Administrator and execute command to create service.

Now, if you open services, you should see that EterlogicVspeService startup type is Automatic. If needed, reboot your computer.

Useful commands (to be executed in CMD as Administrator):
  • Start service: net start EterlogicVspeService
  • Stop service: net stop EterlogicVspeService
  • Delete service: sc.exe delete EterlogicVspeService

Below is a short video demonstrating the steps above.
