On April 8, 2014, Microsoft ended support for Windows XP, the operating system that powered the overwhelming majority of computers for a stretch of time. Microsoft gave plenty of warning that this day would come, and trying to maintain the security of a 13-year-old product is no easy feat. SysAid found 75% of customers still run at least one XP machine, exposing them to security threats. 15% of American companies are running more than half of their machines on Windows XP; 27% of U.S. corporate computers still run the OS. Corporations have a responsibility to protect their customers, employees and investors.”]
