The FTC has opened an antitrust investigation against Microsoft, according to several reports that back up previous reporting by the Financial Times.

It claims to have opened an investigation into allegations that Microsoft violated antitrust law in multiple segments of its business, including its public cloud, AI, and cybersecurity product lines. One segment that has caught particular interest is how Microsoft packages its cloud products with the company's office and security tools, according to the New York Times.

As it informs, the aggressive move comes even as the FTC's chair, Lina Khan is likely to leave once Donald Trump enters office.

It is unclear if Trump will continue President Joe Biden's push to rein in big tech companies. Under Biden, the FTC sued Amazon and Meta, accusing them of stifling rivals, while the Justice Department sued Google over its dominance in ad technology and Apple for making it difficult for customers to leave its product ecosystem.
