i've got win xp 64bit and i've had no troubles but recently the activex that runs when you go to the ms update site disappeared. it used to work or be there. how could this have happened? and how can i fix it? i'm not sure if this is related but my system restore functions have disappeared off the menu too, i did install pc doc pro 5, since removed, and advanced sys care pro, did these take away that option from the menu? how can i get that back?
