Earlier today I used my computer as usual. Than later on tonight i entered my password to login and all of a sudden i get this message:
The user Profile Service service failed to logon.
User profile cannot be loaded.

I found this video that helped me to fix the issue

but everything was switched back to its standard settings. All my history and settings are gone. Why did it happen? How can I regain all my settings back?
