You can check this... -

@Whiler That just controls what options Windows offers you when you press CTRL+ALT+DEL. -

You don't Block Ctrl+Alt+Delete. -

I haven't tried (and I don't plan to...). Does someone know what happens if all options are removed? (does it still display sth.?) -

You cannot do this. The Secuencia de atención segura (the official Windows name for CTRL+ALT+DEL) is handled in kernel mode and it would be a humungous security hole if user mode apps were able to change what happens when the user sends the SAS.

I'm not sure about NT6 but in NT5 (Win2k, WinXP) there is nothing special about Ctrl+Alt+Del other than that it was registered as a global hotkey (via RegisterHotKey()) by the SAS window in winlogon.exe, which is a user-mode process. You could easily intercept it once you injected your code into that process. - moritz-beutel

Sure, when WinLogon still used GINA DLLs to process SAS notifications. That went away in Windows Vista. - Rémy Lebeau
