Proceedings began earlier in the afternoon with a lantern parade featuring children from St George's School and the Egham Brass Band.
Dozens of performers including Windsor Glee Club and the Rock Choir entertained the crowds during the course of the afternoon.
Carols were sung by the Choir of St George's Chapel, Windsor Castle, accompanied by Staines Brass, in the build up to the switch on of the town centre lights.
The lights also illuminate a giant Christmas tree, complete with a gold star, which is gifted by the Crown Estate.

"We had a great night," he said.
He thanked sponsors Macdonald Windsor Hotel for all their help.
Shoppers also enjoyed an Italian market in the town centre over the weekend.
