How to make Skype start with Windows and not log out the user?

Question

Skype

An elderly person has Skype to communicate with his daughter and grandson abroad. Last week, Skype on XP died for a long time, and in connection with this, the computer was replaced with Windows 10 Home, a fresh Skype was installed, everything was set up. For two days everything worked fine, and now the person calls and says that when he "clicks on Skype" he says "Create a profile or sign in" every time.
How to make Skype start up with Windows (there is no such checkbox now), it doesn’t go out on the “cross”, but minimizes to tray (on my two computers it does just that and you can only exit it by logging out), and if everything logged out, the next time you start it automatically logged in?
