How to copy/create a reg key to every user in hkey_current_user?

Hey Guys

Does anyone know how I can create a reg key that only get installed once for every user in hkey_current user?
I've heard I can create one in hklm and from there it can be copied to hcu ?

Thanks.

Usuallly when you want to create a registry key that applys to all users you create it in HKLM.

It depends on the program that uses the key, Office for example needs to use HKCU.
