I've created an app in Visual C# with a Form.

I need that form must be always on top and fullscreen (of course, center). The users must be submit the form to use computer (no Alt+F4, no ALT+TAB).

I tried to set the TopMost property to "True" and I set the form to fullscreen (but the contents remain on the top-left corner, like initial dimensions, and the user can switch between app with keyboard).

Is that possible? Essentially I want a lockscreen.

Thank you!

Regarding Ctrl + alt + del, it's not possible to disable. However, as stated elsewhere, you may want to consider IE Kiosk mode. https://support.microsoft.com/en-gb/kb/154780
