More than 7.33 million visitors came to Windsor last year bringing more than £578million to the town's economy.
The tourists, attracted by sites such as Windsor Castle and Legoland, have helped protect Windsor from the full force of the recession.
Figures from Duport Business Confidence Report reveal a seven per cent rise in net company growth in Windsor during the first half of the year.
While the town was affected by the recession, showing a dip during the first half of 2009, the figures have been climbing ever since, said the report.
Managing director of Duport.co.uk, Peter Valaitis, said: "Windsor did suffer during the recession, but its lively housing market, proximity to London and excellent tourist offering mean the town has weathered the economic storm remarkably well.
"Net company growth is currently rising, and with the UK economy set to come out of recession, the future looks bright for Windsor."
