Nine lawsuits have already been filed against companies in the U.S., the Middle East and Eastern Europe, charging that they received the software under false pretense and then smuggled it into the United States.
Microsoft claims that hundreds of thousands of discounted software packages were obtained by illegal means. The company is not taking action against end users who may have obtained the software, which is labeled "Student Media" and "Not for resale."
