I haven't been able to find any suitable fix for this on line, so hopefully someone can help out. On my PC I have my admin account, and three other family user accounts. All options to switch user were working until a few days ago, but have now disappeared, so we are unable to switch between users.
At the windows lock screen only my account and password box appears. From the Start menu, clicking on my icon only brings up Change Account Settings, Signout and Lock. Signing out doesn't make any difference, the other accounts still do not appear. Also I can only login to my admin account using my Microsoft account password, not the local password.
All the accounts are enabled, and I've tried various settings recommended online (amend registry settings, Local Users and Groups etc), but none have worked. Any ideas what might have caused this and what else I can try?
