Deploy policies to enable applications	Learn how to sign WDAC policies and how to deploy WDAC and AppLocker policies to enable apps execution on Windows SE devices.	03/07/2023	tutorial	✅ <a href="https://learn.microsoft.com/windows/release-health/supported-versions-windows-client" target="_blank">Windows 11 SE, version 22H2 and later</a>

Deploy policies to enable applications

Once the policies are created, you must deploy them to the Windows SE devices. WDAC and AppLocker policies can be deployed via Intune, but WDAC policies must be signed before they can be deployed.

This article describes how to sign WDAC policies and how to deploy WDAC and AppLocker policies to enable apps execution on Windows SE devices.

Sign WDAC supplemental policies

Important

This section will be updated when the process using Azure CodeSigning for CI policy is released in April.

Deploy WDAC supplemental policies

Policies can be deployed via Intune using a custom OMA-URI.

Tip

To prevent these policies from being applied to non-Windows SE devices, you can create and target a group with only Windows 11 SE devices in it, or use assignment filters.

Deploy WDAC policies using Mobile Device Management

Troubleshoot WDAC policies

Deploy AppLocker policies

Intune doesn't currently offer the option to modify AppLocker policies. The deployment of AppLocker policies can be done using PowerShell scripts deployed via Intune.

You can create a PowerShell script that stores the contents of the policy in a variable, then use the Set-AppLockerPolicy PowerShell command to merge it. Here's a sample function for the task:

function MergeAppLockerPolicy([string]$policyXml)
{
  $policyFile = '.\AppLockerPolicy.xml'
  $policyXml | Out-File $policyFile
  Write-Host "Merging and setting AppLocker policy"
  Set-AppLockerPolicy -XmlPolicy $policyFile -Merge -ErrorAction SilentlyContinue
  Remove-Item $policyFile
}

Warning

Intune deploys a script with the AppLocker policy to set Intune Management Extension as a managed installer on all Windows 11 SE devices enrolled into an Intune EDU tenant. If you want to deploy your own AppLocker policy to set another Managed Installer (in addition to Intune), be sure to use the -Merge parameter with Set-AppLockerPolicy. The -Merge parameter ensures that your policy plays well with Intune's AppLocker policy. Without using the -Merge parameter, it will result in issues with apps not getting tagged properly and their ability to run on impacted devices. To learn more about AppLocker Merge policy, see Merge AppLocker policies.

Once finished, you can deploy the script via Intune. For more information, see Add PowerShell scripts to Windows devices in Microsoft Intune.
