CrowdStrike update causes outages Windows systems worldwide

edited July 20 in Outages

A faulty component in the latest CrowdStrike Falcon update is crashing Windows systems, impacting various organizations and services across the world, including airports, TV stations, and hospitals.

For those already affected, CrowdStrike provides the following workaround steps:

  1. Boot Windows into Safe Mode or the Windows Recovery Environment
  2. Navigate to the C:\Windows\System32\drivers\CrowdStrike directory
  3. Locate the file matching “C-00000291*.sys”, and delete it.
  4. Boot the host normally.

George Kurtz, the President and CEO of CrowdStrike announced a few minutes ago that the company “is actively working with customers” and confirmed that the problems are caused “by a defect found in a single content update for Windows hosts.”
