Doubt with unmanaged client

Hello. I made a group for unmanaged clients e created a package with some features I wanted. I exported it pointing to that group computer mode, unmanaged, etc... My question is... Thats clients of course wont show in that group anyway, right? If this client come to my network it wont show too? And about the license... Doesnt count a license? And the client will stop working, download etc when my license expire???

Thanks
