A special meeting has been organised by the Royal Borough after sweeping decisions were made on Heatherwood Hospital.
The council is urging people to attend the meeting, which will be held in The Pavilion at Ascot Racecourse on Thursday, May 9.
NHS Berkshire chiefs decided on Tuesday last week that the birth centre, rehabilitation ward and the MIU unit will be closed as part of an overhaul of healthcare services.
Councillors will be joined by Windsor MP Adam Afriyie to debate the next steps in what they say is 'the fight to save services for local people'.
Cllr Sayonara Luxton, chairman of the council's adult services and health overview and scrutiny panel, said the NHS used its 'own death throes to kill off' services at Heatherwood.
A petition has also been launched by the council against the cuts, which more than 1,000 have signed in just over a week.
Members of the Save Heatherwood Hospital Campaign are also continuing their fight after condemning the decisions as a 'sham'.
