Nothing works. The test systems are clean installs of Windows 7 and Windows 10. Clean installs. Clean. (So please don't ask me to run sfc /scannow and other Windows repair drivel.) I want to share a single folder in Windows 7 with Windows 10, and vice-versa. I DO NOT want to use File Sharing because it exposes the entire file system to the other system. I have tried the following and none of them worked: 1. Enable SMB1 on Windows 10, but Windows 7 cannot access the folder on Windows 10 (error 0x80004005) 2. Share a folder with "Everyone", but Windows 7 cannot access the folder on Windows 10 (error 0x80004005) 3. For shits and giggles I even disabled Windows Firewall on both systems, but Windows 7 cannot access the folder on Windows 10 (error 0x80004005) If I enable File Sharing, then both systems can see each other, but then the entire file system is exposed to the other system - that is a security no-no. Nope. Can't have that. Does anyone know how to make this work ? WTF - is there like no official documentation whatsoever that explains specifically how the various folder\file sharing options are supposed to work (the difference between SMB [network share], local sharing, etc)? Anyone ?
