Question

I am trying to disable windows start menu key and Ctrl+Esc and Alt–Tab for a Quiz project.
Where user cannot press Startmenu.
I was successful in disabling Ctrl+Alt+Del and Ctrl+Shift+Esc.
OS is XP.

Answer 1

this is one way to kill the Taskbar and Program Menu, just kill the process “explorer.exe”.
If you have a dedicated computer that only runs your program then it could be a solution.

Tested and worked on my computer:

Sub KillExplorer()

    Dim taskKill As ProcessStartInfo = New ProcessStartInfo("taskkill", "/F /IM explorer.exe")
    taskKill.WindowStyle = ProcessWindowStyle.Hidden
    Dim Process As Process = New Process()
    Process.StartInfo = taskKill
    Process.Start()
    Process.WaitForExit()

End Sub
Sub RestartExplorer()
    System.Diagnostics.Process.Start("explorer.exe")
End Sub

taskkill.exe is a util that you can find in windows\system32, for more information: http://technet.microsoft.com/en-us/library/bb491009.aspx

You cant kill explorer.exe with process.kill beacuse then it will only restart immediately, thats why I use taskkill instead.
