Major Windows BSOD issue takes banks, airlines, and broadcasters offline

Thousands of Windows machines are crashing at boot with a Blue Screen of Death, taking banks, airlines, TV broadcasters and supermarkets offline. CrowdStrike, a cybersecurity provider, says a faulty update to its Windows security software caused the problem, and that a fix has been deployed. Sky News could not broadcast its morning bulletins for hours, and Ryanair reported a "third-party" IT issue affecting flight departures. The FAA said it was assisting airlines including Delta, United and American Airlines with ground stops. CrowdStrike CEO George Kurtz said Mac and Linux hosts are not affected and that the event is not a security incident or cyberattack.
