**Microsoft Releases Step-by-Step Guides to Fix CrowdStrike Blue Screens of Death**

In a bid to address widespread user concerns, Microsoft has released comprehensive step-by-step guides aimed at resolving Blue Screen of Death (BSOD) issues caused by CrowdStrike’s Falcon sensor. These BSOD incidents, which can be highly disruptive and detrimental to productivity, have prompted both Microsoft and CrowdStrike to collaborate closely to find a solution that ensures system stability and security.

**Understanding the Issue**

The BSODs related to CrowdStrike’s Falcon sensor primarily stem from conflicts between the sensor and certain Windows kernel operations. These conflicts can cause the operating system to crash, leading to the dreaded blue screen. Users experiencing these issues often find their systems unexpectedly restarting or shutting down, causing data loss and interrupting critical workflows.

**Step-by-Step Guides to Resolution**

To help users navigate and resolve these issues, Microsoft has released detailed guides that encompass various troubleshooting methods. Here’s an overview of the key steps involved:

1. **Identifying the Problem**

– **Check Event Viewer:** Users are advised to open the Event Viewer by typing `eventvwr` in the Windows Run dialog. Under the “Windows Logs” section, they should look for critical errors that coincide with the BSOD occurrences. Event IDs related to CrowdStrike or kernel crashes are primary indicators.
– **System Reliability History:** Accessing the Reliability Monitor (`reliabilitymonitor` in the Run dialog) can provide a timeline of system crashes and failures, helping pinpoint when the issue started.

 2. **Updating Software**

– **Update Windows:** Ensure the latest Windows updates are installed. Navigate to Settings > Update & Security > Windows Update, and click “Check for updates.”
– **Update CrowdStrike Falcon Sensor:** Visit the CrowdStrike website or use the Falcon management console to ensure that the latest version of the sensor is deployed. CrowdStrike frequently releases patches to address compatibility issues.

3. **Adjusting System Settings**

– **Disable Fast Startup:** Fast Startup can sometimes cause conflicts with driver initialization. To disable it, go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > uncheck “Turn on fast startup.”
– **Driver Verification:** Use the Driver Verifier Manager (`verifier` in the Run dialog) to identify problematic drivers. However, this tool should be used with caution as it can exacerbate the issue temporarily to help identify the root cause.

4. **Reconfiguring CrowdStrike Sensor**

– **Modify Sensor Settings:** Through the Falcon management console, users can adjust sensor settings to reduce the load on system resources. This includes modifying scan frequencies and the aggressiveness of the sensor.
– **Exclude Specific Applications:** If the BSODs are linked to specific applications, configure the Falcon sensor to exclude these applications from active scanning.

 5. **Uninstall and Reinstall CrowdStrike**

– **Uninstall Falcon Sensor:** As a last resort, users can uninstall the Falcon sensor by navigating to Control Panel > Programs and Features > Uninstall a program, and then selecting CrowdStrike Falcon Sensor.
– **Clean Installation:** After uninstalling, restart the system and perform a clean installation of the latest sensor version from the CrowdStrike website or management console.

 6. **Seeking Professional Help**

– **Contact Support:** If the issue persists, contacting Microsoft Support or CrowdStrike Support is recommended. Both companies offer dedicated support services to help resolve complex issues.

 7. **Documenting and Reporting**

– **Feedback Hub:** Microsoft encourages users to report their findings and experiences through the Windows Feedback Hub. This helps both Microsoft and CrowdStrike to track recurring issues and improve their products.
– **CrowdStrike Support Portal:** Submitting detailed reports, including system logs and error codes, through the CrowdStrike Support Portal can expedite the resolution process.

 

Microsoft’s release of these step-by-step guides signifies a proactive approach to resolving the BSOD issues affecting users of CrowdStrike’s Falcon sensor. By following these comprehensive troubleshooting steps, users can mitigate disruptions and enhance system stability. Both Microsoft and CrowdStrike remain committed to addressing these challenges and ensuring a seamless user experience.
