Harry’s surname is Mountbatten Windsor, nothing complicated.
In fairness to the numerous people here and elsewhere who assume it is complicated, most hail from the United States or another country where surname customs are extremely simple. Most Americans, for example, have a single, one-word surname which is used regardless of context. For example, prior to marriage, Meghan Markle would have used "Markle" and only "Markle" as her surname everywhere: on legal documents, on bank accounts, on her resume, on her social media, while being introduced by a mutual friend at a party, etc.
The longstanding custom that British princes/princesses and British peers/peeresses usually are referred to without a surname (for example, as "HRH The Prince of Wales" or "His Royal Highness The Prince William Arthur Philip Louis The Prince of Wales") but in certain informal settings use the territorial designation from their title as an unofficial surname ("William Wales") and in certain legal papers use their legal surname ("William Arthur Philip Louis Mountbatten-Windsor") - and that none of this involves any changes to names or titles, but is merely a tradition of using different forms of identification in different contexts - is more complicated than the average person from many countries is accustomed to.
