Win 7 Ultimate Network Query

[BEJ]

I'm a single user on a single computer. Although I have four computers, I have no desire to have them networked or to share any files, etc.
I simply want to connect to the internet on this single computer (which is working fine at this time)
The problem is being able to change the name of a "user" that has appeared in Windows Explorer.
I am "User1" in the Start Menu
"User1" is also listed as the "Administrator"

In the "Network & Sharing Center"

Basic Network
User------Network1--------Internet
(This Computer)

In "Window Explorer"

Local Disk (C (down to)
"Users"
Public
user (Note small "U")

I simply want to change "user" (small "u") to "User" (capital "U") or to
"Administrator". So far, I have had no success whether trying through
"Network & Sharing" or any other means.
I understand this is a simple problem, but please tolerate my "ANALNESS"
Thanks for your time and trouble.

Enable the administrator account, and delete the user account.

That's what I usually do on my Windows 7 machines...not a great idea, but if I muck my computer up, it IS my own fault.

By the way welcome

Thank you for the reply and links. This "user" under "User1" must be ingrained and out of reach. I won't go into the boring details of my three hours hassle with Win 7, but I will just say "I'm now very happy to see /user as an account".
Thanks for your time and trouble.
