Microsoft outage workaround: How to deal with the Blue Screen of Death, caused by CrowdStrike?

 

Windows computers around the world are being hit by the dreaded Blue Screen of Death (BSOD) thanks to an outage caused by services provided by cybersecurity firm CrowdStrike. The issue has impacted everyone from banks to airlines, with flights grounded, grocery carts abandoned, and productivity even lower than usual for a Friday.


 

Fortunately, CrowdStrike has since announced at 2:30 a.m. ET 07/19.24 that it has identified the update causing the issue and rolled it back. The company also offered a workaround for anyone having problems.

 

To fix the problem,

1.       Boot Windows into Safe Mode or the Windows Recovery Environment

2.       Go to:  %WINDIR%\System32\drivers\CrowdStrike directory

3.       Locate the file matching “C-00000291*.sys” and delete it.

4.       Reboot normally.

 

"CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts," CrowdStrike CEO George Kurtz said on X. "Mac and Linux hosts are not impacted. This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed."

 

To prevent for enterprise environment,

·         Backup!

·         Test updates before deploying them to production.
