Display a custom URL message when users try to run a blocked app

Applies to

• Windows 10

This topic for IT professionals describes the steps for displaying a customized message to users when an AppLocker policy denies access to an app.

Using Group Policy, AppLocker can be configured to display a message with a custom URL. You can use this URL to redirect users to a support site that contains info about why the user received the error and which apps are allowed. If you do not display a custom message when an apps is blocked, the default access denied message is displayed.

To complete this procedure, you must have the Edit Setting permission to edit a GPO. By default, members of the Domain Admins group, the Enterprise Admins group, and the Group Policy Creator Owners group have this permission.

To display a custom URL message when users try to run a blocked app

1. On the Start screen, type gpmc.msc to open the Group Policy Management Console (GPMC).
2. Navigate to the Group Policy Object (GPO) that you want to edit.
3. Right-click the GPO, and then click Edit.
4. In the console tree under Policies\Administrative Templates\Windows Components, click File Explorer.
5. In the details pane, double-click Set a support web page link.
6. Click Enabled, and then type the URL of the custom Web page in the Support Web page URL box.
7. Click OK to apply the setting.
