The U.S. Federal Trade Commission has opened a broad antitrust investigation into Microsoft, including of its software licensing and cloud computing businesses, a source familiar with the matter said on Wednesday.

The probe was approved by FTC Chair Lina Khan ahead of her likely departure in January. The election of Donald Trump as U.S. president, and the expectation he will appoint a fellow Republican with a softer approach toward business, leaves the outcome of the investigation up in the air.

The FTC is examining allegations the software giant is potentially abusing its market power in productivity software by imposing punitive licensing terms to prevent customers from moving their data from its Azure cloud service to other competitive platforms, sources confirmed earlier this month.
