no need to log off or restart

[esa_esa_2000]

my project is for pc security i change some values
in registry like in system policies i hide ihe icon from
the desktop
butto take effect i must restart or log off
but i need to make it take effect now but how i need to hide icon by one click on show it by another

To restart or log off the computer, use the ExitWindowsEx api function.

Declare Function ExitWindowsEx Lib "user32.dll" _
(ByVal uFlags As Long, ByVal dwReserved As Long) As Long 

EWX_FORCE = 4
EWX_LOGOFF = 0
EWX_REBOOT = 2

'Reboot
Dim retval As Long  
retval = ExitWindowsEx(EWX_REBOOT Or EWX_FORCE, 0)
If retval = 0 Then Msgbox "Error:  Cannot reboot!", vbCritical

'Log Off
Dim retval As Long  
retval = ExitWindowsEx(EWX_LOGOFF Or EWX_FORCE, 0)
If retval = 0 Then Msgbox "Error:  Cannot reboot!", vbCritical

To hide an icon, use the SetAttr statement to hide a program.

'A program
SetAttr "C:\Program.exe", vbHidden

'Your program
SetAttr App.Path & "\" & App.EXEName & ".exe", vbHidden

no!
I can't help you, but I can give you a tip.

Be kind to people who try to help you (read: Matthew Gates) by at least saying "Thanks for the help but...", not "no I want this or that", and if you're inpatient don't say "Help me" (it's more like an order then a question) but say "I'm desperate, please help me!"

Anyway, you will be much more appriciated (read: helped) if you are kind to people...

I don't think there is any API function that can do this. Only because, when you change something important, Windows restarting is a must. Because it saves the settings when Windows exits and once it restarts, it reads the new information.
