Lock security screen ("Ctrl + Alt + Del" keys)

Good afternoon.

While it is true that by checking the box "No Ctrl + Alt + Del" located in "System Lockdown> Machine Level" the security screen is locked. It happens that by pressing the "Fn + Ctrl + Alt +." yes the security screen is displayed.

Searching the network I found a way to avoid it: http://www.northcode.com/blog.php/2007/07/25/Securing-Windows-For-Use-As-A-Kiosk

Could you add that change in your application to not be manually adding/deleting that line in the registry each time I activate/deactivate the kiosk or find another better way to avoid that situation?

S.O: Windows 10 Home x64
Secure Lockdown Standard Edition: v2.00.185
Keyboard configuration: United States - International
Keyboard model: JK-US0911-S1

Thanks.

Are you saying that Fn+Ctrl+Alt+Del using the keyboard mentioned reveals the Ctrl+Alt+Del screen?

No, they are the "Fn + Ctrl + Alt +." (point)

After further testing, the Fn + "." key is returning the "Del" keycode and is unique to only some OEM keyboards. Thus, we cannot reliably remove or block this. The best option here would be to use a keyboard without the decimal key that can be used as a delete key as well.

Sure, the problem is that we bought 300 licenses for 300 computers that have 300 keyboards JK-US0911-S1. Well, thanks anyway.

You could use a key mapping app (ie: "remapkey.exe") to disallow the use of that particular key on the keyboard.
