Released from captivity after the war he proceeded to Vienna, where he first performed at the Konzerthaus and founded his own dance orchestra in 1946. His swing concerts became increasingly popular in Allied-occupied Austria. Winter could sign a recording contract and his orchestra was a guest in several Austrian radio shows. In
1948 he recorded the song Und jetzt ist es still, composed by Hans Lang, which, translated into English by Bert Reisfeld (It's Oh So Quiet), was covered by Betty Hutton in 1951 and popularized by Björk in 1995.
In the 1950s Winter performed in several revues and variety films with stars like Marika Rökk, but also played with jazz musicians like Hans Koller and Joe Zawinul. In 1960 he performed at the Eurovision Song Contest in London. His German entry Du hast mich so fasziniert (''You fascinated me so much'')" written by Robert Stolz finished seventh out of thirteen. In 1977 he became Kapellmeister of the highly traditional Austrian Hoch- und Deutschmeister military orchestra.
Winter continued to perform in concerts and TV shows into middle age. He died in Vienna, aged 87.
