Don't know how to hide the CTRL key of the keyboard :P :), but this hides the taskbar.

Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Private Const SW_SHOW = 5
Private Const SW_HIDE = 0

Private Sub Form_Load()
Dim lhWnd As Long

'Get the handle of the taskbar
lhWnd = FindWindow("Shell_TrayWnd", vbNullString)

'Hide the task bar
ShowWindow lhWnd, SW_HIDE

'Pause for 5 seconds
Sleep 5000

'show the task bar
ShowWindow lhWnd, SW_SHOW
End Sub

To disable the Task Manager, create the following key in the registry:

HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableTaskMgr = dword:1

Incase you don't want to mess with the clients registry, you can use FindWindow API to keep a look out for the Task Manager window and close it by sending a message, if it is open. You may also want to look at the following sites...
