On my Win 10 computer I have two windows user accounts. One for me and one for my son. We both also have steam accounts. How can I get steam to auto start and login using the correct steam user based on the windows user. Right now steam just uses the user that last used steam. I find it hard to believe steam cannot handle this, but I cannot find a way to do it. I would like to be able to go to any of my Win 10 machines and login and have steam login as the correct user.
