FYI Ramster, you can not use a copy of XP for more then 1 machine.
We bought 1 copy when it came out and put it on 2 pc's and the 2nd one would only go as far as registration when it was already installed and registered.
I called MS and asked what’s up and got a smart ass tech who told me he could have me arrested... well, that conversation was really interesting, I dared him left and right to come and arrest me and called him a pussy a few times.
So count on another $90 for another reg key, I even tried a hacked reg key which didn’t work.
