Karoline Knotten of Norway completed the podium in third.
Preuß already had a third place finish from the 12.5km mass start at the season opener in Kontiolahti, Finland and the win in Hochfilzen is only the second one of her career.
She was leading after prone, slipped into third position after one penalty in standing, but rebounded with a very fast last loop.
“I was simply on a flow. I’m very, very happy and also surprised that even with a mistake it was enough to win,” she said.
Bø returns to winning ways
Norwegian Bø finished the previous season with four consecutive individual wins, but left Kontiolahti empty-handed, with his best result a second place in the 15km race.
But the overall World Cup champion tasted victory again – his 10th in Hochfilzen – despite one missed shot as he finished the 10km sprint in 24:23.1 minutes, 4.2 seconds ahead of team-mate Sturla Holm Lægreid.
France’s Fabien Claude was third, beating Endre Strømsheim and Vebjørn Sørum to deny Norway a podium sweep.
The men’s and women’s pursuit is scheduled for Saturday.
