 # ApplicationControl CSP
 
-Windows Defender Application Control (WDAC) policies can be managed from an MDM server through ApplicationControl configuration service provider (CSP). This CSP provides expanded diagnostic capabilities and support for [multiple policies](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-application-control/deploy-multiple-windows-defender-application-control-policies) (introduced in Windows 10, version 1903). It also provides support for rebootless policy deployment (introduced in Windows 10, version 1709). Unlike [AppLocker CSP](applocker-csp.md), ApplicationControl CSP correctly detects the presence of no-reboot option and consequently does not schedule a reboot.
-Existing WDAC policies deployed using AppLocker CSP’s CodeIntegrity node can now be deployed using ApplicationControl CSP URI. Although WDAC policy deployment via AppLocker CSP will continue to be supported, all new feature work will be done in ApplicationControl CSP only.

+## PowerShell and WMI Bridge Usage Guidance
+
+The ApplicationControl CSP can also be managed locally from PowerShell or via SCCM's task sequence scripting by leveraging the [WMI Bridge Provider](https://docs.microsoft.com/windows/client-management/mdm/using-powershell-scripting-with-the-wmi-bridge-provider).
+
+### Setup for using the WMI Bridge
+
+1. Convert your WDAC policy to Base64
+2. Open PowerShell in Local System context (through PSExec or something similar)
+3. Use WMI Interface:
+
+    ```powershell
+        $namespace = "root\cimv2\mdm\dmmap"
+        $policyClassName = "MDM_AppControl_Policies"
+        $policyBase64 = …
+    ```
+
+### Deploying a policy via WMI Bridge
+
+Run the following command. PolicyID is a GUID which can be found in the policy xml, and should be used here without braces.
+
+```powershell
+    New-CimInstance -Namespace $namespace -ClassName $policyClassName -Property @{ParentID="./Vendor/MSFT/ApplicationControl/Policies";InstanceID="<PolicyID>";Policy=$policyBase64}
+```
+
+### Querying all policies via WMI Bridge
+
+```powershell
+Get-CimInstance -Namespace $namespace -ClassName $policyClassName
+```
