It seems like only government agencies and penny-pinching businesses are still using Windows XP. Wait - I take that back! I still use WinXP in a Virtual Box but its completely shut off from the internet. Why? So I can still watch TiVo movies I recorded before the cable channels locked all that down! At any rate, the less you are connected the safer you are. Won't be long before we're living in caves wearing tinfoil hats. Jeez...
Probably start with the tinfoil bespoke suits, those are next!
