Which means « Not everybody is authorised to create the users' profile ». A bad translation indeed, but I'm used to bad translations here and there in Windows...

Tout le monde n'est pas autorisé à créer le profil des utilisateurs.
I know that previously existing profiles won't be affected.
What I want is that system-wide wireless profiles are protected from unauthorised tampering such as change, deletion or adding another system-wide wireless profile. That's what setting createalluserprofile enabled=no used to do in W8, now it's ineffective.
IIRC there's a way to define wireless profiles by policy, maybe these would still be protected, I will have to check this again. Other advices are welcome !
