The "Microsoft Blue Screen" incident occurred, with multiple banks and airlines reporting technical issues, and United Airlines, American Airlines, and Delta Air Lines suspending flights.
Financial Times July 19, 2017, Microsoft Corp. reported that its Microsoft 365 applications and services were experiencing outages, affecting businesses and users worldwide. "We are investigating an issue that is affecting users' ability to access various Microsoft 365 applications and services," according to the website monitoring software Downdetector on July 19. Japanese users reported problems with Microsoft 365. As of 1:35 p.m. local time, there were over 2,800 reports of the outage, with 69% of the reports related to Onedrive.
Microsoft support center staff said that for the mass blue screen issue, most of the blue screens are caused by the installation of third-party antivirus software, and the blue screen caused by the update of the antivirus software has been confirmed. If the modification of the drive file name is invalid, it is suggested to contact the IT department of the company for further processing.
Microsoft Blue Screen was trending on Weibo this afternoon.
Many netizens shared pictures of their blue screens, with many showing the "csagent.sys" error. The problem also affected Windows users in multiple regions worldwide, with some network engineers saying it was related to the antivirus platform CrowdStrike, which caused blue screens in New Zealand, Australia, Japan, and India.
Some engineers tested and said that entering safe mode, renaming the C:\windows\system32\drivers\crowdstrike folder to another name, and restarting the computer could temporarily solve the problem.
