 George V continued a process of more gradual modernisation , assisted by his wife , Mary of Teck , who had a strong interest in furniture and decoration . Mary sought out and re @-@ acquired items of furniture that had been lost or sold from the castle , including many dispersed by Edward VII , and also acquired many new works of art to furnish the state rooms . Queen Mary was also a lover of all things miniature , and a famous dolls ' house was created for her at Windsor Castle , designed by the architect Edwin Lutyens and furnished by leading craftsmen and designers of the 1930s . George V was committed to maintaining a high standard of court life at Windsor Castle , adopting the motto that everything was to be " of the best " . A large staff was still kept at the castle , with around 660 servants working in the property during the period . Meanwhile , during the First World War , anti @-@ German feeling led the members of the Royal Family to change their dynastic name from the German House of Saxe @-@ Coburg and Gotha ; George decided to take the new name from the castle , and the Royal Family became the House of Windsor in 1917 .
