+# Enable and configure the Block at First Seen feature
+
+**Applies to:**
+
+- Windows 10
+
+You can use PowerShell to perform various functions in Windows Defender. Similar to the command prompt or command line, PowerShell is a task-based command-line shell and scripting language designed especially for system administration, and you can read more about it at the [PowerShell hub on MSDN](https://msdn.microsoft.com/en-us/powershell/mt173057.aspx).
+
+For a list of the cmdlets and their functions and available parameters, see the [Defender cmdlets](https://technet.microsoft.com/en-us/library/dn433280.aspx) topic.
+
+PowerShell cmdlets are most useful in Windows Server environments that don't rely on a graphical user interface (GUI) to configure software. 
+
+> **Note:**  PowerShell cmdlets should not be used as a replacement for a full network policy management infrastructure, such as [System Center Configuration Manager](https://technet.microsoft.com/en-us/library/gg682129.aspx), [Group Policy Management Console](https://technet.microsoft.com/en-us/library/cc731212.aspx), or [Windows Defender Group Policy ADMX templates](https://support.microsoft.com/en-us/kb/927367).
+
+PowerShell is typically installed under the folder _%SystemRoot%\system32\WindowsPowerShell_.
+
+
+**Use Windows Defender PowerShell cmdlets**
+
+1. Click **Start**, type **powershell**, and press **Enter**.
+2. Click **Windows PowerShell** to open the interface. 
+    > **Note:**  You may need to open an administrator-level version of PowerShell. Right-click the item in the Start menu, click **Run as administrator** and click **Yes** at the permissions prompt.
+3. Enter the command and parameters.
+
+To open online help for any of the cmdlets type the following:
+
+```text
+Get-Help <cmdlet> -Online
+```
+Omit the `-online` parameter to get locally cached help.
