setupp.ini PID= needed from WinXP Pro UPGRADE

[anonymous]

I have a case where I have a valid paid for Windows XP Upgrade Key but only have access to Retail XP Pro media.  I think it may be possible to change the PID= line in setupp.ini to allow use of an upgrade key.  Can someone who has access to a retail, upgrade, windows xp pro disc look at the file \"i386setupp.ini\" and post the PID= line?  Thanks

change the key to last 3 key to 335 at the setupp.ini then try using ur own key

Does this also works in the same way with XP Home (i think so) and, for example does it works always this way?

Because i\'ve a retail oem cd, but i want to build a retail
from this, so i just make Pid=51882335, rebuild the CD bootable, and it works then with retail keys?
