Travelling criminals are using cycle paths to make their way across Royal Borough borders before committing crimes.
Police are carrying out extra patrols on countryside bridleways to prevent them from entering borough land, and carrying out operations to keep them away.
He said outsiders committed 73 per cent of crimes in the area from April 1, 2011 to March 31, 2012 with figures showing a similar pattern this year.
Supt Gilbert said most are travelling from Slough and officers are carrying out special operations working with Slough Police to keep an eye on the roaming criminals.
He said: "We have always had the problem with cross borders and suffer from criminals coming into the borough, especially in Windsor, and then committing crimes.
"They use cycle paths through The Brocas to come across using bikes or walking and we are doing patrols down cycle paths and special operations to stop them."
Supt Gilbert also said the number of serious acquisitive crimes in the borough from April 1 to July 23 this year dropped by 61 to 1,040, compared to 1,101 for the same period last year.
Burglaries were down to 195 from 215, violence against people dropped 61 to 413 from 474, and theft of vehicle to 49 from 69.
The only rise of the four serious types of crime was theft from vehicle, which rose by 40 offences to 383 from 343.
Supt Gilbert added: "It is encouraging, and crime is going in the right direction and we want to make the borough a place criminals don't want to come.
"My plea for the summer is for people is to lock their doors and shut their windows and do not leave anything insecure."
