Once everything is set up and working. Create a shortcut of the .exe file (Right-click -> send to -> desktop)
Then press Win+R and run shell:common startup
This will one a file explorer window.
Cut from desktop and paste the shortcut in the new window.
Doing this should automatically automatically start when you start and log in.
Just press Win+R and run shell:common startup and finally delete that shortcut.
If you temporarily want to stop it, open task manager -> start-up apps -> You'll see the 'startkomga.exe' which you can disable.
