i understand there are verious naughty ways to bypass the windows verification but the easiest is not to use windows auto updater or goto microsoft for your updates i understand that you can download update packages like this one (big download)
http://ap.manroweb.co.uk/filez/AutoPatcher_XP_Apr06_ENU_Full.exe
or if you want individual updates, go to
http://windowsupdate.62nds.com/
where you can download updates without microsoft spying on you (which is what they're doing) or checking your windows version or putting cripping codes onto your pc to disable your *illegal* copys from working.
it is not ileagal to get your updates & downloads from third parties as these are the very same microsoft ones just no checking or spying.
i won't condone the use of ileagal copy's of software on this site by any of its users or those looking in that is a matter for your own conscience's
(ps:copy this info quick as i suspect it will not be here long !!)
