The Queen does not normally use a surname (she doesn't need a passport or a driving licence for example), but on the few occasions where it has been necessary, i.e. when serving with the ATS during World War II, she has used the surname 'Windsor'.
The British royal family changed their last name from Saxe-Coburg-Gotha to Windsor in 1917.
