Windsor Arch KA I

Founded in Taipa in 1985 under the name Associacão Desportiva Ka I, the club has seven titles to its name: three Liga de Elite titles and four Taça de Macau. They have been one of the best clubs in Macau since their debut in Liga de Elite in 2009.

Led by Japanese midfielder Dan Ito, the club made their debut in Liga de Elite in 2009 season, where they managed to finish in second place in the standings, just behind Lam Pak, while winning their first trophy, Taça de Macau. It continued in 2010 season with a Cup-Championship double and in 2011 season the club became champion for the third consecutive year. The club changes its name before the start of the 2016 season to become Tak Chun Ka I, after about a year known as Windsor Arch Ka I.

Despite its many national titles, the club have so far never taken part in an Asian competition as Macau does not field any team in competitions managed by the AFC then.

As of 2018 season the club became known again as Ka I.

In 2019, the club playing in the 2019 Taça de Macau was disqualified along with Hang Sai for protesting Macau's forfeit against Sri Lanka as a 2022 FIFA World Cup qualifier after the Macau FA's refused their national football team to travel to Sri Lanka to play their second-leg match due to terrorist reasons, which resulted by a 21-18 win for Ka I and a advance to quarter-finals. Due of this controversial match, Ka I and Hang Sai apologize for their gestures but were disqualified from the Macau FA Cup and Chao Pak Kei receive a bye and advance to semi-finals.
