Ok, thanks for responses, rolduz youre right, in fact i can change my W10 key like say george in my fake machine, those are installed with hte last key are upto date dant need to be reinstalled in fact. All new machine ad in group take the new key. so its fine. i have found a trick for dont have to touch my snapins. i made a snapin group Base with the very best of essential. and made some extra group for office soft with licences, opensource, special group for researcher equip etc… i have tested with a machine and she take 2 group with differents snapins in each group if that works i think there is no problem to add a machine to 4 groups.
this is solved my worry.
thanks and keept this module a live !! its so usefull !!
