Updating Windows XP SP2 serial number

Intelliadmin published this earlier today... with all the problems some people have had with the Genuine advantage notification that their copy of Windows may not be legitimate (many reasons for this...) it may be necessary to buy a new copy of Windows and it would be a nuisance to have to reinstall. So, there is a way to just update the serial number to the new copy. The download from Microsoft can be found here and checks the main system files (for patching/changes to circumvent WGA) and then asks for the new Product Key. Reboot and it should have updated the serial number and maybe WGA will let you do updates.

Sorry to be so cynical, but I really wonder how reliable WGA is, I know the writer of the intelliadmin articles seems to think that pretty much all the ones having trouble with it got their copy of Windows at a small shop that essentially pirated copies of windows. I've seen lots of complaints about WGA in recent months and don't know if all of them come down to piracy.

That's probably a discussion for another day though.
