run prg in background

i have a little helper app (nsis script) for me which controls
some files and recover them for me if deleted.
this tiny app is called every 10 mins from the taskplaner
but i have the trouble that this program gets in front
and when i'm playing online in minizes my game. 🙄

so i need some help to get this app working in background
or run minimized itself.

thx
