Can you assist finding out why a certain Windows 10 Home computer claims "the user name or password is incorrect" when trying access it through a local network (using the target computer's own user/password)?
It's not even about specific shares as it happens even when typing \\computer-name itself without any specific shares.
It happens regardless of which device tries to access it (another Windows PC, an Android device, etc.).
Strangely enough, there's another Windows 10 Home computer with exactly the same advanced sharing settings, Windows firewall, default folder shares, etc., that can be accessed flawlessly by typing \\its-computer-name (even through the aforementioned Windows).
Both computers use Microsoft logins and the users/passwords are known.
Do you think it's possible the aforementioned Windows somehow has a local password that is different than its Microsoft password and that's why it fails? Because as soon as I turn off password protected sharing, then everything gets fixed...
I've even tried changing the password just to be sure I know it, but it didn't help.

After struggling, I finally did 2 actions and at least one of them seemed to be the one that fixed it! I can't guarantee which one as I dare not reproduce this.
- Taking on my theory that somehow the Microsoft password didn't match the local password, I've entered the lock screen, cancelled the pin code, asked to unlock via a password instead and entered the Microsoft password.
- User Account Control Settings had a lower setting than the default (in the "good" Windows it was the default), so I brought back the default.
Somehow I got to do both of these together, then Bingo! I could finally use (from multiple devices) the Microsoft user and password to enter \\that-computer!
I can confirm by logging out of the both machines and logging in using password this cured it, using pin and finger print did not
