Google said that the Vista function Instant Search, which allows users to enter a search query and get a list of results from their hard drive, puts rival companies at a disadvantage. Microsoft have now agreed to build an option into Vista which allows users to select a default desktop search program on Windows. They have also agreed to place links inside the Internet Explorer window and in the Start menu to make the default search easier to access.
It was claimed that the Instant Search feature violated the consent decree that monitors Microsoft as part of its settlement with the US government following an antitrust consent decree in 2002.
Microsoft has called Google's complaint baseless and said it was in compliance with the antitrust settlement.
