The Question:
If I install a retail box version of XP on a box that I did not register or
activate
neither by internet or telephone, can a reinstall that version of XP on
another
machine and register and activate it on that one without any conflict?

The Sad Story:
I replaced a crashed hard drive.
I could not find the Gateway OS disc to reinstall XP.
Finally bought a retail box of XP and installed it but did not register it
or activate it.

I found the Gateway OS disc the next day.
I formatted the disc and went back and installed XP from the Gateway OS disc.
Since I never registered or activated the retail box version of XP neither
by internet or telephone, nothing on the retail disc should cause a problem
if I install that copy of XP on another compueter should it?  I can still use
the key again since I did not register it or activate it?
