Sam Billings hammered a career-best 87 and Chris Jordan took four wickets as England skittled the West Indies out for 45 and triumphed by 137 runs in St Kitts.
Choosing to bowl first, the West Indies got the early breakthrough they were looking for as England opener Jonny Bairstow was caught by Devendra Bishoo at backward point off the bowling of Sheldon Cottrell for 12.
Alex Hales, who opened the batting with Bairstow, only made eight runs before he was caught by Carlos Brathwaite at backward square leg off the bowling of Fabian Allen.
England skipper Eoin Morgan also failed to have an impact as he was caught behind off the bowling of Brathwaite for one run.
With Denly being cleaned up by Allen for two runs, England found themselves in trouble at 32/4.
However, Joe Root and Billings came to the rescue as they amassed an 82-run partnership, during which Root brought up his fifty, before he was run out by Allen for 55, which came off 40 balls and included seven boundaries.
Billings and David Willey kept the runs flowing with a 68-run stand before Billings was caught behind off the bowling of debutant Obed McCoy on the last ball of the innings for a 47-ball 87, which included 10 boundaries and three sixes.
Thanks to Billings and Root, England finished on 182/6.
Allen was the pick of the bowlers with two wickets, while Cottrell, Brathwaite and McCoy chipped in with one wicket apiece.
Chasing 183 to win, the West Indies lost opener Chris Gayle early on as he was caught by Root at mid-on off the bowling of Willey for five runs.
Shai Hope was the next to go as he scored seven runs before also being dismissed by Willey.
The West Indies completely imploded after that as they lost wickets in a hurry since Jordan ripped through their middle order.
Shimron Hetmyer and Brathwaite were the top scorers with 10 runs apiece as the West Indies were bundled out for 45, their lowest and the second-lowest Twenty20 International score in history.
Jordan was the most successful bowler with four wickets, while Willey, Adil Rashid and Liam Plunkett claimed two wickets each.
Billings was named Man of the Match.
