To install Winlogon Notification Package you need to add entries in registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify
.
Then you must restart computer so winlogon will read this configuration. Is there a way to force winlogon to refresh this configuration without restarting?
OR
How can I detect that specific Notification Package is not working yet and requires restart? I'm talking about ScCertProp.
