Joe Root hit his second hundred of the Cricket World Cup as England strolled to an eight-wicket win over Southampton on Friday in Southampton.
But it was not all good news for the hosts with injury scares for captain Eoin Morgan and opener Jason Roy.
Root, opening instead of Roy, who appeared to suffer a hamstring injury while fielding and had to leave the field, helped guide England home as they comfortably reached 213-2 in just 33.1 overs after the West Indies had been bowled out for 212.
England's Test captain hit 100 not out to follow his 107 against Pakistan in their second game of the group stages.
He reached three figures off just 93 balls and struck 11 boundaries.
Mark Wood (3-18) and Jofra Archer (3-30) both shone with the ball for England as they never allowed the West Indies to find any momentum.
Nicholas Pooran (63) and Shimron Hetmyer (39) put on 89 for the fourth wicket, while Chris Gayle hit a typically brisk 36 off 41 balls, but those were the high points of an innings that lasted just 44.4 overs.
England wrapped things up without their captain Morgan, who left the field with a back spasm, but like Roy he was not needed with the bat in the reply.
Root and Jonny Bairstow (45) put on 95 for the first wicket and then he and Chris Woakes (40), who was promoted up the order, put on 104 for the second wicket as England emphatically claimed their third win of the group stages.
They are next in action on Tuesday in Manchester against Afghanistan, while the West Indies will look to bounce on Monday at Taunton against Bangladesh.
