# Turn off Windows Defender

{% hint style="warning" %}
Windows Defender must be turned off temporally to run our services, otherwise injection wont work.
{% endhint %}

### Before you begin

* Save your work. A restart may be required.
* Note the setting's original state. Re-enable it immediately after testing.

### Windows 10 and Windows 11

{% stepper %}
{% step %}

#### Open Windows Security

Select **Start**. Search for `Windows Security`, then open it.

You can also select **Settings → Privacy & security → Windows Security** in Windows 11. In Windows 10, select **Settings → Update & Security → Windows Security**.
{% endstep %}

{% step %}

#### Open Virus & threat protection

Select **Virus & threat protection**. Under **Virus & threat protection settings**, select **Manage settings**.

#### Turn off real-time protection

Set **Real-time protection** to **Off**. Select **Yes** if Windows requests administrator approval.

Keep this window open while you install or test the trusted software.

### If the setting turns back on

This is expected. Windows restores protection automatically after a short period or restart.

### Turn off VBS and Hyper-V

Virtualization-based security (VBS) and Hyper-V can prevent some software from running. Turn them off only when required. Restart Windows after completing these steps.

{% hint style="warning" %}

Set **Memory integrity** to **Off**. Select **Yes** if Windows requests approval.
{% endstep %}

Search for `Windows features`. Open **Turn Windows features on or off**.

Clear these options if they are enabled:

* **Hyper-V**
* **Windows Hypervisor Platform**
* **Virtual Machine Platform**
  {% endstep %}

{% step %}

#### Restart Windows

Select **OK** to apply the Windows feature changes. Restart your device when prompted.
