Three people in Illinois have filed a lawsuit against Microsoft, claiming that its Windows 10 update destroyed their data and damaged their computers.
The complaint [PDF], filed in Chicago's US District Court on Thursday, charges that Microsoft Windows 10 is a defective product and that its maker failed to provide adequate warning about the potential risks posed by Windows 10 installation – specifically system stability and data loss.
Microsoft "failed to exercise reasonable care in designing, formulating, and manufacturing the Windows 10 upgrade and placing it into the stream of commerce," the complaint claims. "As a result of its failure to exercise reasonable care, [the company] distributed an operating system that was liable to cause loss of data or damage to hardware."
The attorneys representing the trio are seeking to have the case certified as a class action that includes every person in the US who upgraded to Windows 10 from Windows 7 and suffered data loss or damage to software or hardware within 30 days of installation. They claim there are hundreds or thousands of affected individuals.
