git push => git: 'credential-winstore' is not a git command.

Hi,

Windows 10
git version 2.17.0.windows.1

I'm having a problem very similar to this one:
https://stackoverflow.com/questions/11693074/git-credential-cache-is-not-a-git-command
One of the comments on the question suggests this command:

git config --global --unset credential.helper


This did help me, because previously Git was trying to authenticate me
with the Microsoft account I use to log into my Windows, which is
unrelated to the account I need to use to push code. And it removed
one of the two "git: 'credential-winstore' is not a git command."
messages I was receiving.

But I still get one of them, so I tried reinstalling Git for Windows
with the credential helper disabled, but that didn't help. Then I ran
this command:

git config -e


And couldn't find any mention of [credential].

What can I do to get rid of this annoying message (and, for all I
know, potential symptom of a larger problem)?

Thanks,
Chris
