India entered the three-match series with their eyes on the bigger picture, which includes the Asia Cup and the home World Cup in October-November.
It did not really matter at the Brian Lara Stadium in Trinidad where India racked up 351-5 after being put into bat.
They then returned to bundle out West Indies for 151 in 35.3 overs with only Alick Athanaze (32) and Gudakesh Motie, who made 39 not out, offering some resistance.
After Mukesh Kumar (3-30) wrecked the West Indies top order, Shardul Thakur (4-37) hollowed out the bottom half as India registered their 13th consecutive ODI series win against West Indies.
West Indies captain Shai Hope said the target was not beyond their reach but they lacked consistency.
