Set Registry Key on HKCU:\Software\Policies

Hi, i have a software that needs to add some keys into the registry HKCU:\Software\Policies

But it turns that even this is Current User Key, the user don't have rights to this Key.

I seem to be able to modify everything under HKCU but in this folder the user has only read permissions.

Why?

Is there a way to grant user Full control of this Key and subkeys without giving him Local Admin Rights?

Can i modify this with  a startup script even though this is a HKCU ?

Thanks
