Windsor is about 22 miles (roughly 35–36 kilometers) from Buckingham Palace in London, when traveling by road. The typical driving time is around 35–45 minutes, depending on traffic. If you’re planning public transport, the journey can take about 1 hour to 1 hour 30 minutes with connections, depending on the route you choose. If you’d like, I can tailor this with exact options for your dates, preferred mode (car, train, bus), and whether you’re starting from Windsor Castle or central Windsor.
