What is Prince William's last name? Is it Windsor?

Question

I just wanna know

Answer 1

Under an Order-in-Council in 1960, the non-titled descendants of Queen Elizabeth and the Duke of Edinburgh were given the surname Mountbatten-Windsor, combining the surnames of Elizabeth and Philip. However, although titled, the Queen's children have all decided to use the surname also in honour of their father. For their banns for their first marriages, both William's aunt, Anne, Princess Royal and his own father, Charles, Prince of Wales, used Mountbatten-Windsor rather than Windsor. Mountbatten-Windsor is now officially treated as being the surname of all descendants of the Queen and the Duke except those, like the children of the Princess Royal, who have a new paternal surname (in that case, "Phillips").

As with Royal Family tradition, Prince William used "Wales" as a last name during his years of education, as has Prince Harry. William's York cousins in turn use "York" (other Royal Families also use their parents' title as their own working surname). Past precedent, however, is that such title-surnames are dropped from usage in adulthood, with either title alone or name and Mountbatten-Windsor being used on legal documents and banns of marriage.

Answer 2

Prince William Arthur Philip Louis Mountbatten-Windsor

Answer 3

Prince William of Wales can use Wales or Mountbatten-Windsor as his last name;Wales,because it names his Royal lineage,and Mountbatten-Windsor because it's the family name.
Go to http://www.royal.gov.uk for a complete explaination.
"The Royal Family name of Windsor was confirmed by The Queen after her accession in 1952. However, in 1960, The Queen and The Duke of Edinburgh decided that they would like their own direct descendants to be distinguished from the rest of the Royal Family (without changing the name of the Royal House), as Windsor is the surname used by all the male and unmarried female descendants of George V.

It was therefore declared in the Privy Council that The Queen's descendants, other than those with the style of Royal Highness and the title of Prince/Princess, or female descendants who marry, would carry the name of Mountbatten-Windsor.

This reflected Prince Philip's surname. In 1947, when Prince Philip of Greece became naturalised, he assumed the name of Philip Mountbatten as a Lieutenant in the Royal Navy.

The effect of the declaration was that all The Queen's children, on occasions when they needed a surname, would have the surname Mountbatten-Windsor.

For the most part, members of the Royal Family who are entitled to the style and dignity of HRH Prince or Princess do not need a surname, but if at any time any of them do need a surname (such as upon marriage), that surname is Mountbatten-Windsor.

The surname Mountbatten-Windsor first appeared on an official document on 14 November 1973, in the marriage register at Westminster Abbey for the marriage of Princess Anne and Captain Mark Phillips.

A proclamation on the Royal Family name by the reigning monarch is not statutory; unlike an Act of Parliament, it does not pass into the law of the land. Such a proclamation is not binding on succeeding reigning sovereigns, nor does it set a precedent which must be followed by reigning sovereigns who come after.

Unless The Prince of Wales chooses to alter the present decisions when he becomes king, he will continue to be of the House of Windsor and his grandchildren will use the surname Mountbatten-Windsor."

Answer 4

It's a little unclear - the family name is Mountbatten-Windsor, but supposedly those in directly line to the throne use only Windsor. Personally, he's been using Wales as a last name in his military unit.
