{% step %}

### Check Current Blocklist Status Via PowerShell (Optional)

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

```powershell
Get-CimInstance -Namespace root\Microsoft\Windows\CI -ClassName Win32_DeviceGuard
```

* Look for:

`UserModeCodeIntegrityPolicyEnabled`

`KernelModeCodeIntegrityPolicyEnabled`
{% endstep %}

{% step %}

### Disable Blocklist in Windows Settings (if available)

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

*(If it is **greyed out**, continue on)*
{% endstep %}

{% step %}

### Disable the Blocklist via Registry Command (All Windows Editions)

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

```powershell
reg add HKLM\SYSTEM\CurrentControlSet\Control\CI\Config /v VulnerableDriverBlocklistEnable /t REG_DWORD /d 0x000000 /f
```

* You should see: **"The operation completed successfully."**
* Restart your PC.
  {% endstep %}

{% step %}

### 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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://gandyhacks.gitbook.io/gandyhacks-docs/individual-guides/vulnerable-driver-blocklist.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
