How do I change the name of a computer on network?

[none]

I named it "Rich" but for some reason windows added a bunch of junk after
this. (rich-w1dqfxk5ct)

sorry to inundate with questions. I added "Rich" but I don't know how to
delete the original.

control panel >user accounts

This sounds like you made a new user account. There can only be one
computer name. To delete the user account you don't want, log in with a
different user account with administrative privileges. Go to the User
Accounts applet in Control Panel and delete the unwanted account.
