The Conservative candidate was 30-year-old Charles Mott-Radclyffe, who had not previously contested a parliamentary election.
However, many by-elections were contested by independent or minor party candidates, and in Windsor William Douglas Home, the younger brother of the future Prime Minister Alec Douglas-Home, stood as an "Independent Progressive" candidate, opposing Winston Churchill's war aim of an unconditional surrender by Germany.
[1] Douglas-Home, a Second lieutenant in the Royal Armoured Corps, had previously contested the Glasgow Cathcart by-election in April 1942.
On a low turnout, Mott-Radclyffe held the seat for the Conservatives, but with a majority of only 17%, a surprisingly good result for Douglas-Home.
Mott-Radclyffe served as Windsor's MP until he retired from the House of Commons at the 1970 general election Douglas-Home went on to contest the Clay Cross by-election in April 1944, where he came a poor third, and was later imprisoned for a year with hard labour after being court-martialled for refusing to fight in the attack on Le Havre after the allied forces had refused a German request to suspend hostilities to allow civilian evacuation.
