How to recover from the Blue Screen on Windows systems caused by CrowdStrike

CrowdStrike’s latest product update has caused a Blue Screen of Death error on Windows computers. In this guide, we show you how to recover from the Blue Screen error on Windows systems caused by CrowdStrike.

CrowdStrike is a cybersecurity firm that equips organizations via Falcon and other platforms, prevents breaches, attacks, and fixes vulnerabilities, which should be deployed mostly in enterprise environments. If it is your own computer, it is unlikely to be attacked.


Here is the official solution to fix the the blue screen from CrowdStrike company:

  • Boot your Windows PC into Safe Mode or Windows Recovery Environment.
  • Go to C:\Windows\System32\drivers\CrowdStrike
  • Locate and delete file matching "C-00000291*.sys"
  • Boot normally
Another way is to prevent CrowdStrike from starting using either of the following methods:

Method 1:
  • Go into Command Prompt from Recovery options.
  • Navigate to C:\Windows\System32\Drivers
  • Rename CrowdStrike to Crowdstrike_Old
  • Restart the PC.

Method 2:
  • Boot your Windows PC into Safe Mode or Windows Recovery Environment.
  • Go to Windows Registry
  • Edit the following key to disable the csagent.sys from loading.
  • HKLM:\SYSTEM\CurrentControlSet\Services\CSAgent\Start from a 1 to a 4

If you are running Windows on a AWS EC2 instance, you can try the following method:
  • Detach the EBS volume from the impacted EC2
  • Attach the EBS volume to a new EC2
  • Fix the CrowdStrike driver folder as per the workaround suggested by CrowdStrike
  • Detach the EBS volume from the new EC2 instance
  • Attach the EBS volume to the impacted EC2 instance
The above method can also be applied for Windows instances running on Google Cloud Platform.

and If you need any Windows 10/11 or Office 2021/ Microsoft 365, you can get it from the Microsoft reseller Keyingo.com with a good price
