Automated CrowdStrike BSOD Workaround in Safe Mode using Group Policy · GitHub

Posted by jpluimers on 2024/07/19

Most affected organisations have found out the hard way why out of band management is important.

Automated Workaround in Safe Mode using Group Policy

You can set up a GPO to run a script during Safe Mode. Here’s how you can do this:

  1. Create the PowerShell Script

    Create a PowerShell script that deletes the problematic CrowdStrike driver file causing BSODs and handles the Safe Mode boot and revert:

    # CrowdStrikeFix.ps1
    # This script deletes the problematic CrowdStrike driver file causing BSODs and reverts Safe Mode
    
    $filePath = "C:\Windows\System32\drivers\C-00000291*.sys"
    $files = Get-ChildItem -Path $filePath -ErrorAction SilentlyContinue
    
    foreach ($file in $files) {
        try {
            Remove-Item -Path $file.FullName -Force
            Write-Output "Deleted: $($file.FullName)"
        } catch {
            Write-Output "Failed to delete: $($file.FullName)"
        }
    }
    
    # Revert Safe Mode Boot after Fix
    bcdedit /deletevalue {current} safeboot
    
  2. Create a GPO for Safe Mode

    • Open the Group Policy Management Console (GPMC).
    • Right-click on the appropriate Organizational Unit (OU) and select Create a GPO in this domain, and Link it here....
    • Name the GPO, for example, CrowdStrike Fix Safe Mode.
  3. Edit the GPO

    • Right-click the new GPO and select Edit.
    • Navigate to Computer Configuration -> Policies -> Windows Settings -> Scripts (Startup/Shutdown).
    • Double-click Startup, then click Add.
    • In the Script Name field, browse to the location where you saved CrowdStrikeFix.ps1 and select it.
    • Click OK to close all dialog boxes.
  4. Force Safe Mode Boot Using a Script

    Create another PowerShell script to force Safe Mode boot and link it to a GPO for immediate application:

    # ForceSafeMode.ps1
    # This script forces the computer to boot into Safe Mode
    
    bcdedit /set {current} safeboot minimal
    Restart-Computer
    
  5. Create a GPO to Apply the Safe Mode Script

    • Open the Group Policy Management Console (GPMC).
    • Right-click on the appropriate Organizational Unit (OU) and select Create a GPO in this domain, and Link it here....
    • Name the GPO, for example, Force Safe Mode.
    • Right-click the new GPO and select Edit.
    • Navigate to Computer Configuration -> Policies -> Windows Settings -> Scripts (Startup/Shutdown).
    • Double-click Startup, then click Add.
    • In the Script Name field, browse to the location where you saved ForceSafeMode.ps1 and select it.
    • Click OK to close all dialog boxes.
  6. Apply the GPOs

    • Make sure the Force Safe Mode GPO is applied to the affected computers first.
    • The computer will boot into Safe Mode and execute the CrowdStrikeFix.ps1 script.
    • Once the issue is fixed, the script will revert the boot settings to normal mode.
