OK, this works, tested it now on a Windows 7 machine. I am now assuming the shared folders on your husband's Windows 7 PC should be shared with everyone on your home network with full rights.
Ask your husband to stop sharing any folder he is now sharing from his Windows 7, then share it again with these two commands in an elevated (administrator) Command Prompt.
net share AnyName=X:\SharedFolder /GRANT:Everyone,Full
AnyName = Any name he wants to use, the name you will see as share name when you browse the network
X:\SharedFolder = Full path (drive:\foldername) of the shared folder
icacls X:\SharedFolder /grant:r *S-1-1-0:F
The first command shares a folder with everyone on your network, the second one adds so called NTFS rights to everyone; each user on any Windows PC has a called SID, security identifier, the one we used here (S-1-1-0) means "all users" or "everyone".
That's it. You should now be able to see the share AnyName when browsing the Windows 7 PC on network .
Four times happily divorced myself, I know how reluctantly we men take tech advice from our wives. If he has doubts to remove shares and do the above just because you ask it, ask him to test it first with a new share sharing a nonsense folder .
Please let us know how it went.
