This transferred to the Borough of Slough a small polling district from Surrey and another from Buckinghamshire to form Colnbrook and Poyle This new ward (since renamed Colnbrook with Poyle) was selected for the Windsor constituency, though involved two polling districts (the typically three-four subdivisions of wards). 2010–present: Further to the Fifth Periodic Review, the composition of the constituency is:- The Borough of Bracknell Forest wards of Ascot, Binfield with Warfield, Warfield Harvest Rise, and Winkfield and Cranbourne; The Borough of Slough Colnbrook with Poyle ward; and The Borough of Windsor and Maidenhead wards of Ascot and Cheapside, Castle Without, Clewer East, Clewer North, Clewer South, Datchet, Eton and Castle, Eton Wick, Horton and Wraysbury, Old Windsor, Park, Sunningdale, Sunninghill and South Ascot.

Members of Parliament Burgesses in the English Parliament, 1510–1707 As there were sometimes significant gaps between Parliaments held in this period, the dates of first assembly and dissolution are given. Where the name of the member has not yet been ascertained or (in the 16th century) is not recorded in a surviving document, the entry unknown is entered in the table. The Roman numerals after some names are those used in The House of Commons 1509–1558 and The House of Commons 1558–1603 to distinguish a member from another politician of the same name.
