A few things. I've got Password-protected sharing turned *on* in Windows 10 and LibreElec (Kazaq's latest s905x build) accesses it without any problems. You can tell Windows not to require regular password changes. I can't remember where you do this, but Google will. What I did was to create an account specifically for Samba access and then hide that account without ever signing into it. How to hide accounts? There's one registry key to change. Again, Google will come to your rescue. If you do it that way, there will be minimal impact on your system. No superfluous folder structure under 'Users', No superfluous user name on your sign-in screen. Hth.
