This topic for IT professionals describes the steps for displaying a customized message to users when an AppLocker policy denies access to an app.
|
|
|
|
With the help of 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 don't display a custom message when an app 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.
