-## Usage guidance  
+## Microsoft Endpoint Manager (MEM) Intune Usage Guidance  
 
-To use ApplicationControl CSP, you must:
-- Know a generated policy’s GUID, which can be found in the policy xml as `<PolicyTypeID>`.
-- Convert the policies to binary format using the ConvertFrom-CIPolicy cmdlet in order to be deployed. The binary policy may be signed or unsigned.
+For customers using Intune standalone or hybrid management with Configuration Manager (MEMCM) to deploy custom policies via the ApplicationControl CSP, refer to [Deploy Windows Defender Application Control policies by using Microsoft Intune](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-application-control/deploy-windows-defender-application-control-policies-using-intune)
 
-If you are using hybrid MDM management with System Center Configuration Manager or using Intune, ensure that you are using Base64 as the Data type when using Custom OMA-URI functionality to apply the Code Integrity policy via uploading the binary file.
+## Non-Intune Usage Guidance
+
+In order to leverage the ApplicationControl CSP without using Intune, you must:
+
+1. Know a generated policy’s GUID, which can be found in the policy xml as <PolicyID> or <PolicyTypeID> for pre-1903 systems.
+2. Convert the policies to binary format using the ConvertFrom-CIPolicy cmdlet in order to be deployed. The binary policy may be signed or unsigned.
+3. Create a policy node (a Base64-encoded blob of the binary policy representation) using the certutil -encode command line tool.
+
+Below is a sample certutil invocation:
+
+```cmd
+certutil  -encode WinSiPolicy.p7b WinSiPolicy.cer
+```
+
+An alternative to using certutil would be to use the following PowerShell invocation:
+
+```powershell
+[Convert]::toBase64String($(Get-Content -Encoding Byte -ReadCount 0 -Path <bin file>))
+```
+
+### Deploy Policies
 
-### Deploy policies
 To deploy a new base policy using the CSP, perform an ADD on **./Vendor/MSFT/ApplicationControl/Policies/_Policy GUID_/Policy** using the Base64-encoded policy node as {Data}. Refer to the the Format section in the Example 1 below.
 
 To deploy base policy and supplemental policies:
-- Perform an ADD on **./Vendor/MSFT/ApplicationControl/Policies/_Policy GUID_/Policy** using the Base64-encoded policy node as {Data} with the GUID and policy data for the base policy.
-- Repeat for each base or supplemental policy (with its own GUID and data).
+
+1. Perform an ADD on **./Vendor/MSFT/ApplicationControl/Policies/_Policy GUID_/Policy** using the Base64-encoded policy node as {Data} with the GUID and policy data for the base policy.
+2. Repeat for each base or supplemental policy (with its own GUID and data).
 
 The following example shows the deployment of two base policies and a supplemental policy (which already specifies the base policy it supplements and does not need that reflected in the ADD).

 ### Delete policies
+
+#### Rebootless Deletion
+
+Upon deletion, policies deployed via the ApplicationControl CSP are removed from the system but stay in effect until the next reboot. In order to functionally do a rebootless delete, first replace the existing policy with an Allow All policy (found at C:\Windows\schemas\CodeIntegrity\ExamplePolicies\AllowAll.xml) and then delete the updated policy. This will immediately prevent anything from being blocked and fully deactive the policy on the next reboot.

 To delete an unsigned policy, perform a DELETE on **./Vendor/MSFT/ApplicationControl/Policies/_Policy GUID_/Policy**.
 
-> [!Note]
->  Only signed things should be able to update signed policies. Hence, performing a DELETE on **./Vendor/MSFT/ApplicationControl/Policies/_Policy GUID_/Policy** is not sufficient to delete a signed policy.

+You can use Microsoft Endpoint Manager (MEM) Intune to configure Windows Defender Application Control (WDAC). Intune includes native support for WDAC, which allows you to configure Windows 10 client computers to only run Windows components and Microsoft Store apps, or to also allow reputable apps as defined by the Intelligent Security Graph (ISG). Using the built-in policies can be a helpful starting point, but many customers may find the available circle-of-trust options to be too limited. 
 
-You can use Microsoft Intune to configure Windows Defender Application Control (WDAC). You can either configure an Endpoint Protection profile for WDAC, or create a custom profile with an OMA-URI setting. By using an Endpoint Protection profile, you can configure Windows 10 client computers to only run Windows components and Microsoft Store apps, or let them also run reputable apps as defined by the Intelligent Security Graph.
+In order to deploy a custom policy through Intune and define your own circle of trust, you can configure a profile using Custom OMA-URI. Beginning in 1903, Custom OMA-URI policy deployment leverages the [ApplicationControl CSP](https://docs.microsoft.com/windows/client-management/mdm/applicationcontrol-csp), which has support for multiple policies and rebootless policies. Custom OMA-URI can also be used on pre-1903 systems to deploy custom policies via the [AppLocker CSP](https://docs.microsoft.com/windows/client-management/mdm/applocker-csp).
