This is the best summary I could come up with:
Airlines, payment processors, 911 call centers, TV networks, and other businesses have been scrambling this morning after a buggy update to CrowdStrike's Falcon security software caused Windows-based systems to crash with a dreaded blue screen of death (BSOD) error message.
Microsoft and CrowdStrike both say that "the affected update has been pulled," so what's most important for IT admins in the short term is getting their systems back up and running again.
If rebooting multiple times isn't fixing your problem, Microsoft recommends restoring your systems using a backup from before 4:09 UTC on July 18 (just after midnight on Friday, Eastern time), when CrowdStrike began pushing out the buggy update.
If these simpler fixes don't work, you may need to boot your machines into Safe Mode so you can manually delete the file that's causing the BSOD errors.
We'll continue to track recommendations from Microsoft and CrowdStrike about fixes as each company's respective status pages are updated.
"We understand the gravity of the situation and are deeply sorry for the inconvenience and disruption," wrote CrowdStrike CEO George Kurtz on X, formerly Twitter.
