I logged into windows (@hotmail) on my computer in the current user. Passwords and their list on all sites where passwords are registered have disappeared. All my other settings are working. On my second browser, I have all my passwords and settings. Only in the first browser my passwords disappeared.

Similarly, my saved passwords are lost after the format.

What should I do so that passwords are not lost in format and similar account movements?

Please don't make suggestions like opera sync and keeppass.
