During its antitrust battle with the Justice Department and 19 states, Microsoft showed more restraint--at least publicly--in its business strategies and tactics. But given George W. Bush's election and signs that the Court of Appeals would partly deflate the government's victory in the trial court, the software behemoth has returned to the hard-charging Microsoft of old. For example, for several months Microsoft has been aggressively rolling out its .Net software-as-a-service strategy, seen as a threat to companies ranging from Sun Microsystems to AOL Time Warner. In addition, the company has been advancing long-standing initiatives on all fronts, including an Internet service code-named HailStorm, the upcoming Windows XP operating system, and other products which employ so-called bundling tactics that partially sparked the current antitrust case. Iowa attorney general Tom Miller said that due to Microsoft's more aggressive tactics, the Justice Department and 19 states will be keeping a close eye on the software maker's conduct. "The company's recent announcements regarding (Windows) XP and HailStorm indicate to us that Microsoft may be repeating its efforts to maintain and extend its monopoly even more broadly into the Internet."
