CrowdStrike crash

There is a global systems outage that appears to affect Windows computers running CrowdStrike security software. Systems that have updated are crashing with a BSOD (Windows Blue Screen of Death). If this issue affects you, there is a quick fix.

How to fix the BSOD

  • Boot into Safe Mode or into the Windows Recovery Environment
  • Go to C:\Windows\System32\drivers\CrowdStrike
  • Find and delete C-00000291*.sys
  • Reboot

How to boot into Safe Mode

  1. Interrupt Normal Boot Process:
    • When your PC starts, wait for the Windows logo to appear.
    • As soon as it does, forcefully shut down your computer by holding down the power button.
    • Repeat this process two more times.
    • On the fourth boot, Windows will detect the interrupted startup and offer you advanced options.
    • Choose “Advanced options,” then “Startup Settings.”
    • Click “Restart.”
    • Now, press the corresponding number key (usually 4, 5, or 6) to select the desired Safe Mode option:
      • Press 4 or F4 for minimal Safe Mode.
      • Press 5 or F5 for Safe Mode with Networking (useful if you need internet access).
      • Press 6 or F6 for Safe Mode with Command Prompt.
