# Vulnerable Driver Blocklist

## 🚫 How to Disable the Vulnerable Driver Blocklist&#x20;

> ⚠️ **Note:** The **Vulnerable Driver Blocklist** prevents known insecure kernel-mode drivers from loading. Disabling it reduces protection and should only be done for compatibility reasons (e.g., unsigned drivers, legacy mods, certain anti-cheats).

***

### 📌 Step 1: Check the Current Blocklist Status

**✅ Via PowerShell (Optional)**

1. Press `Start`, type `PowerShell`, right-click it, and select **Run as Administrator**.
2.  Run this command:

    ```powershell
    Get-CimInstance -Namespace root\Microsoft\Windows\CI -ClassName Win32_DeviceGuard
    ```
3. Look for:
   * `UserModeCodeIntegrityPolicyEnabled`
   * `KernelModeCodeIntegrityPolicyEnabled`

***

### 🖥️ Step 2: Disable Blocklist in Windows Settings (if available)

1. Go to **Settings** → **Privacy & Security** → **Windows Security** → **Device Security**.
2. Click **Core Isolation details**.
3. Find **Microsoft Vulnerable Driver Blocklist** and toggle it **Off**.

> 💡 If the switch is **greyed out**, continue to Step 3.

***

### ⚙️ Step 3: Disable the Blocklist via Registry Command (All Windows Editions)

1. Press `Windows + X`, then choose **Terminal (Admin)** or open **Command Prompt as Administrator**.
2.  Run the following command:

    ```cmd
    reg add HKLM\SYSTEM\CurrentControlSet\Control\CI\Config /v VulnerableDriverBlocklistEnable /t REG_DWORD /d 0x000000 /f
    ```
3. You should see:\
   &#xNAN;**"The operation completed successfully."**
4. Restart your PC.

***

### ✅ Step 4: Confirm the Blocklist Is Disabled

After reboot:

* Go back to **Windows Security** → **Device Security** → **Core Isolation Details**
* The **Microsoft Vulnerable Driver Blocklist** should be **Off**
* Or re-run the PowerShell command from Step 1 to verify policy status
