The exquisite wedding took place at St. George's Chapel, the second royal wedding this year, after Meghan Markle and Prince Harry married in May.
Windsor was full of well-wishers when the royal family and a number of big names and celebrities flocked to the chapel to witness the wedding.
Eugenie, 28, looked beautiful in a chic Peter Pilotto low back dress and showed her scars from the scoliosis surgery in a nod to other patients and their surgeons.
As she walked down the aisle, the youngest member of the royal family, 32-year-old Jack Brooksbank, told his bride that she looked "perfect."
Jack spoke first. He said, "I, Jack Christopher Stamp, take you, Eugenie Victoria Helena, to my wife, to have and from that day on, for the better, for the worse: for the rich, for the poor, in sickness and in health; to love and appreciate until death participates us, according to the holy law of God, and I give you my faithfulness.
Princess Eugenie answered in the same way: "I Eugenie Victoria Helena take Jack Christopher Stamp to my husband to have and from that day on, for the better, for the worse: for rich, for the poor, in sickness and in health; to love and appreciate until death participates us, according to the holy law of God, and I give you my faithfulness.
Like her aunt, the late Princess Diana and her cousins Kate, Duchess of Cambridge and Meghan, Duchess of Sussex, Eugenie did not swear to obey her husband.
Diana was the first to break the royal precedent when Queen Elizabeth, at her 1948 wedding, pledged to obey her husband, Prince Philip.
The rest of the ceremony was pretty traditional.
The maid of honor, Eugenie's sister, Princess Beatrice, held a reading before the Great Gatsby.
Outside on the steps of the chapel, the newlyweds kissed as the crowd of well-wishers cheered.
The couple hopped for a short procession through the streets of Windsor in a carriage before going to the Queen's lunchtime reception.
The bride and groom left the reception stylishly and drove off in a real James Bond car, originally made for the James Bond movie Specter.
It was said that Jack breathed relief as he climbed into the driver's seat of the car.
The bride and groom then went to a black evening reception in the royal hut.
On Saturday, the festivities will be continued at another celebration at the Royal Lodge.
This second party will be a festival-style event, complete with fairgrounds Rides and food stalls.
This is organized by Bentleys Entertainment, the same company that David and Victoria Beckham celebrated in 1999.
Vanity Fair has reported that the two celebrations will cost more than £ 100,000 after the Queen's reception, but the Duke and Duchess of York are reportedly paying for the two events.
The couple to have Not confirmed where they will go on honeymoon, but they will certainly look forward to a break from the public eye as they establish themselves as husband and wife.
