Microsoft needs to address this issue for Enterprise customers who 'are' system administrators. Why can't we disable this popup from appearing? We are implementing a KIOSK (that runs a specific webpage) and do not want random Microsoft apps (which we do not care if they try to run) to popup this message to the end-user.

It's very simple, we do not want to display this popup. How can we disable it? We really don't care if some Microsoft store app or random app tries to run and cannot run. We just do not want the system to popup a message on the screen, to an end-user, every time it runs into an app it's not supposed to run.AppLockerPopup

Microsoft, please can you provide a solution?

Thank you!

    Hello

    Thank you for your question and reaching out. I can understand you are having query\issues related to Applocker message.

    As per my knowledge there is no option to completely disable this message pop up.

    However, have the option of customizing this message: https://learn.microsoft.com/en-us/windows/security/threat-protection/windows-defender-application-control/applocker/display-a-custom-url-message-when-users-try-to-run-a-blocked-application

    Update: To prevent this from happening, you need to enumerate all the offending Provisioned AppX applications:

    Get-AppXProvisionedPackage -Online

    Then Remove each one:

    Remove-AppXProvisionedPackage -Online -PackageName <MUST Be the 'PackageName' attribute>

    Since doing this, we have not seen the AppLocker pop-ups.
