Then we need to create two Packaged app Rules one default rule to allow all apps to run and one rule to block the Contact Support app in this scenario.Ħ. Under Computer Configuration\Windows Settings\Security Settings\Application Control Policies\Applocker right-click and select Properties and enable Packaged app Rules and select Enforce rules.ĥ. On a Windows 10 computer running the Enterprise version start Group Policy Editor by typing Edit Group Policy in the search Taskbar.Ĥ. This service must be started for the Applocker policies to be enforced on the client computers.ģ. Under Computer Configuration\Policies\Windows Settings\Security Settings\System Services change the startup to Automatic for the Application Identity Service. Create a new Group Policy for this test.Ģ. Here are the steps for creating a Group Policy to block Contact Support, the same steps would be used to block Microsoft Edge and Windows Feedback if that is a requirement for you as well.ġ. So I ended up creating the Applocker policy locally on a Windows 10 computer and then export it and then import it on a Windows 2012 R2 server with the Group Policy Management MMC installed. The challenge with that right now is there is no RSAT for Windows 10 available yet so creating the policy is a a bit of a challenge. So this method could be used instead of uninstalling the apps as the end result for the end-user is basically the same if they haven’t logged on to the computer before the policy is applied. If the user have logged on to the computer before the Applocker policy is applied the applications is present but the user can no longer start it, and will get the below message displayed. Blocking them using an Applocker policy is working really well, if the user never logged on to the computer before the Applocker policy is applied the application, in this case Contact support is not installed for the user at all and therefor not present either on start or by using search which is really great! They can be blocked using Applocker instead that is the best workaround I have found. Select and right-click on the category of your choice (Executable Rules) → choose Create New Rule to initiate creating a new rule.I wrote a blog post earlier about how to uninstall built-in apps from Windows 10 CBB using Powershell, however some apps cannot be uninstalled like Microsoft Edge, Contact Support and Windows Feedback. Sounds too risky?Ĭreating rules to deny applications via the Publisher conditions will do the trick if you don’t trust a particular publisher.ġ. When you launch an app, you’re granting the publisher permissions to make changes to your system, especially if the app is constantly connected to the internet. Denying Applications via the Publisher Conditions Note that the steps in creating rules for each category are similar except for the Packaged app Rule. But once you’re confident in creating rules, you can create rules for other categories and see their differences. In this tutorial, you’ll create rules for the Executable Rules category and test if they actually work. The Local Security Policy also plays a part in creating rules to deny apps on your system. Denying apps adds security to your machine since you get to deny access to malicious apps. Now that your default AppLocker rules are in place, you can start creating rules to deny apps. Viewing default executable rules Creating Rules to Deny Applications Open a PowerShell console as an administrator, and run the below command to start the Application Identity service on bootup automatically. Setting the Application Identity Service to start automatically on bootup enforces Windows 10 AppLocker rules.
