Windows XP: how to change computer name without reboot?

Question

Under Windows XP, is it possible to change the computer name without rebooting? If so, how?

Answer 1

I don't believe it is possible. Even Windows 7 still requests a reboot when changing the computer name.

You can say restart later when you change it but I have a feeling the machine will still identify itself as the old name until the next reboot(?).
