The victory was the 85th of his magnificent career, but discounting last year's United States GP when only six cars raced because of a tire dispute, and it was Schumacher's first since the end of 2004.
Alonso leads the drivers' standings with 36 points. Schumacher moved up to second with 21, and McLaren's Kimi Raikkonen, who was fifth on Sunday, dropped to third with 18.
Renault leads the constructors' standings with 51 points to McLaren's 33, and Ferrari's 30.
The fifth race on the 18-race schedule is the European GP at Nuerburgring in two weeks.
