Have 3 Windows instances on a single host and messed up with the login credential. not able to login one of the Windows 10 guest os and could not figure out a way to fix it. Any help is appreciated.
Welcome to the Community,
I can't unfortunately answer the question myself, however you may check e.g. https://www.tenforums.com/ for possible option.
Whatever you try, consider to take a snapshot of your VM(s) prior to trying anything, so that you can always revert to the current state in case something goes wrong.

Usually I would advise people who have this problem to do this with a password reset disk,in my opinion,that is a good solution.
Password reset disk, what is?
Try this:
http://www.kieranlane.com/2012/12/12/resetting-administrator-password-windows-2008/
It should work for all Windows.
If you can log on administrator account then will be able to reset other accounts password.
I'm used to calling it that,but some people like calling it a Windows password reset disk,what it does is reset or remove login password from Windows computer.
If you don't have it,it is best to refer these tutorials.
