I'm trying to make a security screensaver in C# for a hospitol where it is no option to disable CTRL+ALT+DEL the screensaver and all word perfect it can't beclosed by a user by task manager the only way to close this screensaver is by using a key combination however the main issue i got now is that the screensaver gets closed if someone does CTRL+ALT+DEL and then ESC which cancels the SAS screen but as mentioned also the screensaver...

is there a workaround for this to make the screensaver not closeable by either the user and the SAS/GINA/Winlogon.exe?

Thanks for the solution,

Although disableing CTRL + ALT + DEL is somthing we have thought about although its not a option the higher ups dont want to disable CTRL + ALT + DEL because it's required for some medical operations.

besides that i have googled allot but i'm out of solutions this is also the reason why i posted this question .

Im going to assume this is windows forms? if so add a timer in the tick event add this code

C#

private void timer1_Tick(object sender, EventArgs e)
{
  if (!this.TopMost)
   {
     this.TopMost=true;
   }
}

this is just a blunt force way to force the form to be on top of all forms even task manager but still does not handle Ctrl Alt Del
