Global Microsoft Meltdown Tied to Bad Crowdstrike Update

Summary: A faulty software update from Crowdstrike caused Windows machines worldwide to display the "Blue Screen of Death" and become temporarily unusable, disrupting airline travel, financial institutions, hospitals and businesses. Crowdstrike CEO George Kurtz said a fix was deployed and that Mac and Linux systems were unaffected, but the remedy requires booting each machine into Safe Mode or Windows Recovery Environment, deleting the file "C-00000291*.sys" and restarting, so recovery could take time.

Bottom line: The fix has to be applied manually on a per-machine basis, and the update was live for roughly 1.5 hours - long enough for a large number of computers to pick it up, including those on older agent versions where the bug had sat in the driver for some time.
