2nd activation of windows xp

no problem , just do it. phone up no big deal it's
automated., you punch in your # they give you the key.

i just purchased a laptop with no OS and want to install
my retail version of windows xp that i used on my
desktop.

microsoft on phone and have it done or is that not
necessary. laptop does not have internet access. how do i
reuse my win xp disc.
