The 32-year-old, tied on 34 victories with Vreni Schneider ahead of the second event of the weekend on home snow in Austria, produced a storming second slalom run to make history.
With fog descending in the middle part of the course, Schild started slowly before blitzing her way down the latter half to cross the line in what would be a winning time of 1:55.63minutes.
No-one could follow her lead, not even slalom World Cup leader Mikaela Shiffrin, who finished 0.41seconds behind in third with Maria Hoefl-Riesch 0.63 shy in total in third.
Schild's win follows up her victory in Courchevel on December 17, brings her level with Alberto Tomba on the second most slalom World Cup victories ever across both genders and completes a fine weekend for Austria with Anna Fenninger winning the giant slalom.
"It's hard to believe but now for sure the record is mine," Schild said.
"I must admit I felt relieved after Courchevel. I needed to break the jinx. It was making me nervous in the end. Everybody was talking about the record.
"I even noticed in training that there was a before and after Courchevel. I'm much more relaxed now."
Meanwhile across Europe in Bormio, Aksel Lund Svindal demonstrated why he is the reigning downhill World Cup champion, current leader and overall front-runner with victory.
Delayed significantly due to heavy snowfall and low visibility, Svindal produced a storming run, changing up a gear in the last 200 metres, to deny Erik Guay of Canada.
The Norwegian clocked a time of 1:54.08minutes with Guay eventually finished third as Austrian Hannes Reichelt went 0.12 quicker but 0.39 slower than Svindal for second.
Guay took the last downhill World Cup in Val Gardena while Reichelt was victorious last season in Bormio however neither could match Svindal has now won 25 races on the circuit.
