Whenever I return access deny to user with my minifilter, it shows " you’ll need to provide administrator permission…" dialog with admin logo (shield) . Can I just disable this behaiour? I do not want him to press retry(admin shield) or cancel buttons.
Edit: Disabling UAC completely is not an option
This is entirely based on the application behavior in response to your error (i.e. one app might choose to display a UAC dialog, another might simply exit, etc.). Usually your only option is to return a different error status, which of course can lead the app to fail differently. Welcome to the strange world of writing an active file system filter!
