Anya Shrubsole's four-wicket haul helped England bowl out West Indies for a meagre 101 in their final World Cup group game.
Shrubsole took four for 21 to restrict the Windies, who were grateful for a partnership of 58 for the seventh wicket between Kyshona Knight (33) and Shanel Daley (30 not out).
Arran Brindle's introduction to the attack ended any potential fightback before England duly wrapped up the tail in a game they have to win to guarantee progress beyond the group stage.
Despite winning the toss, the Windies struggled to prosper on a seam-friendly surface and they slipped to 31 for six, with Shrubsole and Katherine Brunt making the early breakthroughs.
Charlotte Edwards' side were then held up by Knight and Daley's fifty partnership although neither looked to take the attack to England, with both women going at less than a run every two balls.
Brindle made the breakthrough when Knight was stumped after being out of her ground, while the 31-year-old bowled Shaquana Quintyne for a double-wicket maiden.
Brindle had her third wicket in the next over before Shrubsole claimed her fourth scalp in the 37th over, with West Indies losing their last four wickets for just 12 runs. Their meagre total included 23 wides.
