Google seems to be alleging that "if two pieces of software don't play together, then it must be an anticompetitive tactic of Microsoft's," Helm said. "I don't recall any past antitrust cases asserting something so broad," he said.

Andrew Brust, chief, new technology of consulting firm Twentysix New York, said he used Google's desktop search when it first came out but switched to Microsoft's product when it became available for Windows XP because he preferred it.

"Microsoft chose to integrate into Windows, whereas Google decided to be browser-based," he said. "Plus, at least back then, Google installed its own local Web server as part of the product and I really didn't like all that baggage. Microsoft's was just more useful."
