Winter was born in London on 17 July 1965. His mother, Gregg Mayer, is a New York-born dancer who trained with Martha Graham, and founded a modern-dance company in London in the mid-1960s. His father, Ross Albert Winter, is an Australian who danced with Winter's mother's troupe and co-founded the Mid American Dance Company in St. Louis. His father has English ancestry and his mother is Jewish, of Ukrainian Jewish descent. His family wasn’t observant with their Judaism although he went to Jewish summer camp and learned Yiddish through his grandmother.
Winter received training in dance as a child. When he was five, his family moved to Missouri, where his father ran the Mid-American Dance Company (later, Modern American Dance Company), while his mother taught dance at Washington University in St. Louis. The two divorced in 1973.
In 1978, Winter moved to the New York City area, where he and his mother lived in the city and in Montclair, New Jersey. During this time Winter began performing as an actor on and off Broadway, commuting into New York City.
In 1983, after graduating from Montclair High School, Winter was accepted into the Tisch School of the Arts at New York University, where he majored in film and minored in photography. While at NYU, he met fellow aspiring filmmaker Tom Stern. The two collaborated on a number of 16 mm short films.
Winter began acting professionally at ten years old and spent his teen years on Broadway with supporting roles in productions of The King and I, with Yul Brynner, Peter Pan, with Sandy Duncan, and the American premiere of Simon Gray's Close of Play at the Manhattan Theatre Club, directed by Lynne Meadow.
Winter made his feature film acting debut in the 1985 film Death Wish 3, while still a film student at NYU. He dropped out of film school before his senior year in order to accept a role in the film, The Lost Boys (1987). Winter moved to Hollywood, where he began to write and direct a number of short films and music videos. He continued to find work as an actor, with notable roles in such productions as Ivan Passer's Haunted Summer and Percy Adlon's Rosalie Goes Shopping (1989).
In 1989, Winter found international success when he co-starred with Keanu Reeves, playing William "Bill" S. Preston Esq. in the comedy Bill & Ted's Excellent Adventure, a role he reprised in its 1991 sequel, Bill & Ted's Bogus Journey.
Following the success of Bill & Ted, Winter and creative collaborators Tom Stern and Tim Burns were hired to develop a sketch comedy show for MTV. The result, 1991's The Idiot Box, was a hit for the network in its first season. Winter, Stern and Burns declined an offer to make a second season of the Idiot Box and instead accepted a $12 million deal from 20th Century Fox with Winter and Stern jointly making their feature film directorial debut and Winter starring in the 1993 comedy, Freaked. The film was never widely released, despite positive reviews from The New York Times and Entertainment Weekly.

The film was shown at film festivals worldwide, including Official Selection in the Director's Fortnight at Cannes. The New York Daily News called the film "a claustrophobic mind bender. Winter sustains an aura of creepiness worthy of Roman Polanski." In the New York Times, AO Scott praised the film as "Pure Hitchcockian panic. An arresting example of what a talented filmmaker can accomplish with the sparest of means."
In 2007, Winter directed and acted in the live-action adaptation of the hit Cartoon Network series Ben 10, which aired on Cartoon Network in November 2007 and garnered the highest ratings in the channel's history.
