please note before reading this that what i want to do is completely LEGAL and federal law gives me the right to use this software on both of my computers and that i have no intention of distributing it illigally so i dont want to hear anything about it being unlawful

i just bought a copy of windows xp pro thinking i could install it on both of my computers but aparently mirosoft will only let me put it on one system and i was wondering if anyone knows where to get a WORKING crack for the windows activation...
