I am thoroughly confused at present. Before Windows 10 arrived I set up a Workgroup (as opposed to a Homegroup) at home with three Win7 PCs and a WinXP laptop. All PCs could see and talk to all other PCs without requiring a Username and Password.
Now that Win10 has been released I have installed it on two of our PCs, both in dual boot configs; my husband does not want Win10 on his PC yet and continues to use Win7. However, this now means he cannot see or talk to the Win10 PCs without a Username and Password but I can see and talk to his PC as can the second Win10 PC. However, if either Win10 PC is rebooted into Win7 then the same applies to them. Neither can see or talk to the remaining Win10 PC without a Username and Password. Of course, the two Win10 PCs can also see and talk to one another without requiring a Username and Password. We've never used network usernames or passwords since there are only the two of us in the house.
I have tried reading up about Credentials but I don't have ANY credentials set but I can still see and talk to the Win7 PC as well as the other Win10 PC.
Surely there has to be a way that Windows 7 PCs can be made to see and talk to Win7 PCs without a Username and Password. In this regard if anyone can shine a light on the problem it would be much appreciated, thank you very much. If you need any further information then please let me know and I'll do my best to oblige.
Incidentally, having read this post through several times it looks a little confusing because of liberal use of the phrase "Username and Password" but I hope you understand what I am trying to say and I apologise for any confusion I may cause.
