Lauren Bell started with the ball for England, as the West Indies fell to another defeat during the series.
With all five games already completed, England look set for a whitewash run following a convincing 49-point win at the Kensington Oval.
After opting to bat first, England were limited to 131-8 with Sophia Dunkley leading with 35 balls from 32.
Katherine Brunt (24) and Charlie Dean (20) shared an eighth wicket partnership from 45 runs to help England post 131, after falling to 86-7 after 14 overs.
Sheneta Grimmond and Cherry-Ann Fraser finished with three wickets each as West Indies were sniffed out for a first win of the tour.
But in response, the hosts lost two wickets in the first round, with Bell taking the wickets of Aaliyah Alleyne and Rashada Williams for zero.
Bell had another career-best performance, this time finishing with 4-12. It was backed by the spinners, with Sarah Glenn (1-16), Charlie Dean (2-16) and (2-13) all among the wickets as England played West Indies for just 86 runs.
Sophie Ecclestone also won a new women’s cricket record, with the 23-year-old taking her 56th international wicket this year – the most a woman has ever won in a calendar year.
The victory means England take a 4-0 win in the T20 series, ahead of the final game on the same ground on Thursday.
Sophie Ecclestone said: “I really love this tour, the new head coach coming in has really changed things up a bit, and it was great to see everyone back. After being in the Big Bash it’s great to be back in an England shirt.
“It was a bit of a tricky wicket today, but playing spinners with Glenny [Sarah Glenn] and Deano [Charlie Dean] is great for me and great for the three of us, and I’m glad we’re doing well together. Deano obviously played a T20 in the Ashes and didn’t throw a ball or line up a ball, so I think it’s great that she showed how great she can be.
“Looking ahead to the World Cup they are still amazing to be a part of and the event itself will be amazing, I think the rising squad we have now is amazing and I can’t wait to see what what we can do.
“Jon Lewis has been great for us, I think we needed someone to freshen things up and be able to be able to go out and be positive and give the team everything and not have any worries. if it goes wrong and leave everything on the ground.”
