Deploy policies for applications

This tutorial shows you how to deploy policies for applications.

Sign WDAC policies

Follow the instructions below when you want to sign and deploy your WDAC supplemental policy.

Deploy WDAC 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 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 command to merge it in. Here's a sample function that does that:

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 an EDU customer wishes to deploy their own AppLocker policy to set another Managed Installer (in addition to Intune), please be sure to ensure the -Merge parameter is used with Set-AppLockerPolicy. This will ensure that it plays well with Intune's AppLocker policy. Without using the -Merge parameter when deploying to Windows 11 SE devices, it will result in issues with apps getting tagged properly and their ability to run on impacted devices. Learn more about AppLocker Merge policy: Merge AppLocker policies by using [Set-ApplockerPolicy (Windows) | Microsoft Learn][WIN-7]

Once finished, you can deploy the script via Intune. For more information, see [Add PowerShell scripts to Windows devices in Microsoft Intune][MEM-1].
