The Display a custom message title when device installation is prevented by a policy setting machine setting should be configured correctly. This policy setting allows you to display a custom message title in the notification balloon when a device installation is attempted and a policy setting prevents the installation. If you enable this policy setting, Windows displays the text you type in the Main Text box as the title text of the notification balloon when a policy setting prevents device installation. If you disable or do not configure this policy setting, Windows displays a default title in the notification balloon when a policy setting prevents device installation. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Device Installation\Device Installation Restrictions\Display a custom message title when device installation is prevented by a policy setting (2) KEY: HKLM\Software\Policies\Microsoft\Windows\DeviceInstall\Restrictions\DeniedPolicy\SimpleText
