If you can't switch to Microsoft account in Windows 10 due to 'Another user on this device uses this Microsoft account...' message, here's how to fix.

Previously, we have shared you the fix, if you can’t add Microsoft account to your Windows 10.

Consider a scenario, you added a Microsoft account to your Windows 10. But later you found that you need to create new user account in order to fix some issues. In this hiccup, the older Microsoft account remain intact in the registry. Even though you’ve deleted the older user account manually, sometimes it will be still in registry. So if you now opt to switch newly created account to Microsoft account with same e-mail ID of previous one, you’ll see following message:

Another user on this device uses this Microsoft account, so you can’t add it here.
