Change Computer's Name?

I purchased a refurbished Compaq laptop (from Compaq) that came with Windows XP Home Edition and several other programs (e.g. Norton AV, Microsoft Money, etc.) preinstalled. When I went through the XP setup procedures, it asked me to "name" my computer (in a box where its serial number was displayed). I entered something whimsical (i.e. it seemed like a good idea at the time) but now I've changed my mind (since XP is frequently referring to my laptop by that name) and I would like to change the name. Is there any way that I can re-name my computer without re-installing XP and all the other software on it? I'd be grateful for any help.

Also, will I have to register Windows XP within 30 days to keep it functioning? The Compaq manual mentioned that I would be informed during setup if "activation" was required but it was never mentioned; so I'm wondering if the fact that mine is a refurbished computer means that its XP has already been activated?

I apologize if these are really stupid questions but I'm pretty new to computers (and Windows in particular).

 

Changing Computer name;

Hey Pete,
You directed me here from G4 forum.

I had a different problem there, but I saw this so...


I have my computer just named "main ", But when my documents and setting are displayed it has my full name in there. I think it comes from my user account. I had typed my full name, but my second name is spelled incorrectly. I tried to re-name it, but it tells me I can not re-name this. I went to "Start" and at the top clicked on my user account icon. I was able to re-spell it properly there, but it didn't apply to my account.
Do you know why?
Thanks

PS maybe this is what timescape was referring to.

 

Pete,

Thank you so much for the help and the warm welcome. At the rate I'm going you may be seeing a lot of me around here. This board and its members are a truly wonderful resource.

 

Changing user name;

Thanks for the links Pete. I followed everything to the "T" and wasn't successful.

I got to the last part and couldn't figure out how to actually change the name. I made it all the way in to the registry. I did learn a lot though. Now I have a second user account set up if I need it.

My problem was no big deal, I can handle thing as is.
Now if I can figure out what to do about a stuck pixel (it goes away if I rub it gently, but comes back after a while), but that's for another post

Thanks, you'll be seeing me again.
