Use Desktop Duplication API to capture Logon & Lock Screens

Question

Since Windows 10 doesn't support Mirror drivers, how do I use Desktop Duplication API to capture console at all times i.e. start with logon window, then user's desktop (after the user logs in) and also the lock screen?

Answer 1

Detect desktop Switch event then SetThreadDesktop on the thread that is capturing and make sure you're running as SYSTEM user.
