Option 2
1) Create a special script:

Set objWMIService = GetObject("winmgmts:")
Set colProcessList = objWMIService.ExecQuery _
("Select * from Win32_Process Where Name = 'regedit.exe'")
For Each objProcess in colProcessList
    objProcess.Terminate()
Next
Set WshShell = CreateObject("WScript.Shell")
Dim OpenKey
OpenKey=Inputbox("What is the registry branch you wish to open?")
WshShell.RegWrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Applets\Regedit\Lastkey",OpenKey,"REG_SZ"
