Registry solution needed

Posted on 2002-03-28

I need to do the following:
HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\POLICIES\EXPLORER\RESTRICTRUN.
The restrictrun is not listed in the registry so what I need to do is have some code to place it there? Once restrict run is there, I need code to change it from 0 to 1 and back again for restriction purposes.

I will need the complete working code (module, form)to make this happen.

Thank You

Add a reference to Windows Scripting Host, then simply...

dim WSH As New WshShell
WSH.RegWrite "HKCU\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\POLICIES\EXPLORER\RESTRICTRUN", 1 ,"REG_DWORD"
