:slight_smile: Hi kahchoon :

  How do you know your XP SP1 is NOT "genuine" ?
  Since Microsoft allegedly will stop "issuing" Updates for
  that OS after Oct 10, '06, you may be able to resolve
  any "genuineness" issue with Microsoft on the following
  Microsoft Support Forum :

 http://forums.microsoft.com/genuine/default.aspx?siteid=25 .

 I have heard they can be lenient if someone tells them
 the circumstances on HOW they got the computer !?
 Since we are talking Microsoft Updates, do you have
 KB 892130 ( Win Gen Advantage Validation Tool )
 currently on your computer ? As far as I know, this one
 does NOT cause any annoying popup "messages" ?

 P.S. Would be best to ask Microsoft on those forums
        BEFORE downloading the XP SP2; in fact, I have
        heard it is best to order the SP2 CD on the
        Microsoft site rather than downloading it from their
        site ( less potential problems ) . The CD is FREE,
        though there is a small shipping/handling "fee" .
