On July 19th, network security software company Crowdstrike announced on its support platform that it had received numerous reports of blue screens on Windows computers. The company's engineering department has determined that the issue is related to "content deployment" and has now restored these changes. It is recommended that affected users boot their computers to safe mode or recovery environment, navigate to the C: Windows System32 drivers CrowdStrike directory, find the file that matches "C-00000291 *. sys" and delete it to start the computer normally.
