    Applocker problem with "packaged app" rules in update 2004


    Looks like applocker does not respect "packaged app" rules in update 2004 anymore! Changed it to audit only for now but this will be a security problem. I had this set to signed by Microsoft. But everything got blocked. All windows native apps were blocked too.

    Looking forward to a bugfix.

    Thank you in advance.

    :)

    AppLocker GPOs marked as applied but Rules are not enforced

    Hi Community,

    We have been experiencing a problem with AppLocker GPOs in a Windows 10 Environment.

    The Domain functionality level is: Server 2012R2

    Domain Controllers are running: Windows Server 2016

    Workstations are running: Windows 10 Enterprise Build 17134

    We have 2 GPOs; one containing DLL AppLocker Rules and one containing EXE, Script, Appx etc.. Rules.

    When running a gpupdate /force on an affected workstation and getting the gpresult the GPOs appear to be applied and are marked as winning however the contents of C:\Windows\system32\Applocker files are not being updated and recent rules added to both GPOs
    are not being applied. i.e. a new application which has been whitelisted will not run for the user albeit being specified in the applied GPO.

    Can someone please shed some light into this issue?

    Help is highly appreciated!

    Kind regards,

    Jason

    Reinstall and Re-register Apps in Windows 10  


    So, should I follow those steps to add a rule to allow Windows to install it's own software?

    I guess there isn't a way to turn it off?

    Applocker

    Just curious, but according to the tutorial:

    Use AppLocker to Block Microsoft Store Apps in Windows 10

    did you also create a default rule to allow all packaged apps as well ? ( As far as I understand, the specific deny rule will still take precedence over the rest of the allow-all rule ).

    ( Also, just in case you didn't know, Internet Explorer can be disabled through "Apps & Features" if you don't need IE it for any other purpose. )
