Hiding Host Name from Router

You could try unchecking "Register this connection’s addresses in DNS"
Chapter 9 - Windows Support for DNS

However, I doubt that will work because what you want is completely pointless. If you are so concerned about what someone might learn from a unidentifiable computer name then stuff it full of random junk. But a computer name is just that, a computer name. If it provides personal information well that is your own fault.

Also, tin foil hats are on sale at K-Mart right now. Better hurry before they run out!

information much apprecited guys...

as for wanting to hide private info, believe me, if i wanted that, I would have a different machine and not use g#mail!
I was at the least, interested in the process of controlling windows more than it tends to allow.

And as for my tin foil hat...I am thankfully nowhere near a k-mart

- and regardless, I have a much higher reflectivity mylar cap laying around here somewhere :) (though thinking on it, maybe the scrunched up foil helps add a stealth effect...hmm)

thanks again

You'll have to run the command prompt as administrator.

From that article:

If it is hidden, then you will see Yes to the right of Server hidden.

berilac !

Go to Computer name/Domain changes and in Computer name field hold the alt key and type 255, the Computer name field will appear to be blank but you can click ok, click ok and restart computer.
Then router your connected to or any other device or software will see no Device name for your computer, only your Local IP and MAC Address will be visible, which you can also change.
Worked in Windows 7
