Chief Inspector Lee Townsend, deputy local area commander, speaking yesterday at a police media briefing, said the force received calls from concerned faith groups after Drummer Lee Rigby was killed on May 22.
He said: "There was a ripple affect not only across London, but in the whole community across the royal county.
"There was some concern from Muslims that they could be a victim of an attack after the incident in London."
He said police have increased patrols at faith centres in the borough and outside both army barracks in Windsor after the incident.
Chf Insp Townsend said: "We took steps to reassure our communities we are here to protect them against people seeking retribution."
He also urged members of all sections of the community and faiths to be vigilant against any possible attacks.
