Request: Disable key combination or key

Post by mw »

Greetings. I am deploying PWB 2.11 (x32) on some windows 7 machines. Is there an option in the DisableWindowsGUI addon to prevent users from using the ctrl-alt-del function.

Maybe even just disabling the del key would suffice.
Disabling ctrl and alt doesn't work in my scenario as we use that in the key combination to exit PWB.

Thanks for a great product and I look forward to your response.

The Secure Attention Sequence, also known as Ctrl-Alt-Del, can not be interrupted by an application for security reasons by design. The secure attention key is designed to make login spoofing impossible, as the kernel will suspend any program, including those masquerading as the computers login process, before starting a trustable login operation.

There are thee ways to change this, either by creating a new Graphical Identification and Authentication dynamic-link library (GINA.DLL), by editing the Windows Registry logged on as an Administrator, or by setting the Windows Group Policy.

The first method allow complete control over the SAS, but is messy and can cause other issues.

The second method is easy to do, but can only disable the buttons on the SAS dialog.

The third is essentially the same as the second, but is done through policies.
