How did the computer technician guy get around this?

My computer died, technician said he could upgrade things for me for $500 Australian, now i'm not worried about how good the system is as long as it works so my question is, how did he get around the activation proccess, i have windows xp oem, he changed the motherboard, power supply, ram, case, i had a new hardrive already and it had nothing on it at all so windows had to be installed, i thought it went on a point system and if you change too many critical parts it was as if it was a new computer and would not let you activate it, the guy told me there were ways around that so how did he get around it?? sorry i was so long telling you this.How did the computer technician guy get around this?
there is %26quot;points system%26quot; on xp. I have installed xp probably about 200 times with the same disc and Ive never had problems. Besides if he replaced the motherboard and a bunch of other hardware it was best he reinstalled windows. VISTA on the other hand you can only install once or twice if your lucky.How did the computer technician guy get around this?
That is Windows Vista.... XP does not care if you change critical parts. Windows Vista will ask you to re-activate. And if it was an OEM version, on XP that usually allows re-entry without activationHow did the computer technician guy get around this?
well, if he used an oem disc, microsoft lets you activate a copy of windows three total time as long as no other copy is active. or he could have used an activation crack. the first method is legal the crack is not.How did the computer technician guy get around this?
The program that monitors changes in the computer hardware configuration was on the old hard drive.

If he installed on a new hard drive, then there is no problem with activation because it is a new computer.

He didn't %26quot;get around%26quot; anything, when he installed XP, he just went on line and activated it. Even Microsoft can't keep track of the activation keys and hardware installed on millions of computers around the world.
