Question: Who is the spouse of the individual who lives in the houses in Windsor Castle?

Knowledge 1: Windsor Castle
Windsor Castle survived the tumultuous period of the English Civil War, when it was used as a military headquarters by Parliamentary forces and a prison for Charles I. At the Restoration of the monarchy in 1660, Charles II rebuilt much of Windsor Castle with the help of the architect Hugh May, creating a set of extravagant Baroque interiors that are still admired. After a period of neglect during the 18th century, George III and George IV renovated and rebuilt Charles II's palace at colossal expense, producing the current design of the State Apartments, full of Rococo, Gothic and Baroque furnishings. Queen Victoria made a few minor changes to the castle, which became the centre for royal entertainment for much of her reign. Windsor Castle was used as a refuge by the royal family during the Luftwaffe bombing campaigns of the Second World War and survived a fire in 1992. It is a popular tourist attraction, a venue for hosting state visits, and the preferred weekend home of Elizabeth II. [SEP] Knowledge 2: Wedding dress of Princess Elizabeth
The wedding dress of Princess Elizabeth was worn by the future Queen Elizabeth II at her wedding to Philip Mountbatten, Duke of Edinburgh on 20 November 1947 in Westminster Abbey. Given the rationing of clothing at the time, she still had to purchase the material using ration coupons. The dress was designed by Norman Hartnell. Hartnell's signature was said to be embroidery, and he enjoyed "working with soft, floating fabrics, particularly tulle and chiffon, and with plain, lustrous silks". The dress was made of soft Damascus Prokar, with a high neckline, tailored bodice and a short train.
Knowledge 1: Queen Victoria
Victoria's self-imposed isolation from the public diminished the popularity of the monarchy, and encouraged the growth of the republican movement. She did undertake her official government duties, yet chose to remain secluded in her royal residences—Windsor Castle, Osborne House, and the private estate in Scotland that she and Albert had acquired in 1847, Balmoral Castle. In March 1864, a protester stuck a notice on the railings of Buckingham Palace that announced "these commanding premises to be let or sold in consequence of the late occupant's declining business". Her uncle Leopold wrote to her advising her to appear in public. She agreed to visit the gardens of the Royal Horticultural Society at Kensington and take a drive through London in an open carriage.

[SEP] Knowledge 2: Buckingham Palace
The palace, like Windsor Castle, is owned by the Crown Estate. It is not the monarch's personal property, unlike Sandringham House and Balmoral Castle. Many of the contents from Buckingham Palace, Windsor Castle, Kensington Palace, and St James's Palace are part of the Royal Collection, held in trust by the Sovereign; they can, on occasion, be viewed by the public at the Queen's Gallery, near the Royal Mews. Unlike the palace and the castle, the purpose-built gallery is open continually and displays a changing selection of items from the collection. It occupies the site of the chapel destroyed by an air raid in World War II. The palace's state rooms have been open to the public during August and September and on selected dates throughout the year since 1993. The money raised in entry fees was originally put towards the rebuilding of Windsor Castle after the 1992 fire devastated many of its state rooms. 476,000 people visited the palace in the 2014–15 financial year.
