What acsc_e8_application_control affects

See here page 2 for information on which applocker rules will be configured.

In addition, c:\choco will also be whitelisted for executables to allow chocolatey to run from its default directly. Chocolate is commonly used in conjunction with Puppet on Window for package management. Chocolately


Only apply this module to test nodes initially. Applocker can prevent application from running and could cause outages in production systems.

Audit only mode can now be used to verify applocker rules before they are enforced.

  dll_rules          => 'Enabled',
  script_rules       => 'Enabled',
  packaged_app_rules => 'Enabled',
  start_service      => true,

For more information on how to construct applocker rules, please see documentation.


This module has been tested on

  • Windows Server 2016
  • Windows Server 2019

Windows 10 hasn't been tested, however it expected to work.

It can take a few minutes for applocker to apply policies once running Puppet. Especially when setting up applocker for the first time. I have seen it take over 20 minutes in some cases.
