Need help making a .bat script to edit Userinit in registry

Hello everyone,

I need help building a batch script or vbs to edit Userinit located at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\

What I need is a script to set it back to default which is C:\Windows\System32\userinit.exe instead of whatever non default values are in it.

Any help would be appreciated.

Thanks
