Can ISP (server) see somebody's username?

Hi!

 

Sorry if I started topic in wrong category.

I wonder whether username (User Account Name) which somebody use on his/her computer (with Windows installed) can be seen by ISP or server?

Thank you for responses.

no, just your ip address, and windows version that you are running
