I have a desktop with windows 7 pro, and also a windows 10 home desktop. They have both joined the homegroup and the win 10 can see folders on the win 7. But the win 7 can see nothing on win 10. They have the same homegroup password, but the networks seem different. The win 7 says it's connected to Netwoork 6-Home. The win 7 says it's connected to Network 7-Private.
