The "login" dialog on Windows 95 was just providing network credentials. Windows 95 is a single-user OS. There is no actual login or security.

Technically True.

But there was an optional registry key that prevents the user from doing anything until after you were logged into the network. So practically, it was a login dialog.

But still no security.

Windows 9x does let users have separate profiles with their own files and settings, even if they aren’t super secure.

This, you could literally press escape to login.

The herein linked article discusses disabling that option, and the animated GIF linked at the beginning shows it not working.
