Since the recent Fall Creators Update I'm facing a strange behavior while using Windows 10. My brother and I are using different accounts, both protected by password. When I turn on my PC and sign in, an automatic startup program (the Blizzard Launcher) warns me that it can't start since another user on the same computer is using that app. I thought that it was impossible, my brother's account can't be active if I just turned my PC on.

Actually, if I press the start button and the user icon, it says that my brother is signed in.

Ok, he must have turned the PC off without properly disconnecting the account, I thought, right?

So I let my brother log in his account, sign out, turn the PC off, turn it on again, log in my account. Same problem, his account is already signed in. Without even entering the password.

The same happens if he is the one to login first after booting, he sees me already signed in. If I switch account to mine, I can clearly see that my startup programs are already started and ready.

How is this possible? Windows is booting up accounts without even putting the password in?

Open Settings, Accounts, Sign-in Options.

Sign-in Options

Disable Use my sign-in info to automatically finish setting up my device after an update or restart

Hope that helps. Let's know.

You may also need to change the settings that turn shutting off into hibernate. Windows 10 will go to hibernation instead of shutdown even if you disabled it and asked to shutdown.

You can reach that setting by;

  1. Go to Windows 10 Control Panel.
  2. Go to the Hardware and Sound.
  3. Go to Power Options.
  4. Click "Choose what the power button does" on the left panel.
  5. Click "Change settings that are currently unavailable" and type in the Admin password
  6. Uncheck "Turn on fast startup (recommended)"

The account which got logged in automatically on my machine did not have any password set up.

I tried the solution using Settings and by editing the registry without success.

The solution for me was to enable password login for that account. For details, see solution #1 on https://www.reneelab.com/windows-10-disable-auto-login.html.
