Why is Microsoft patching XP? I thought it was already past EOL?,(reply>), Kalil Olsen <br>Their call I guess. Concern must be so high on this vulnerability that too many organizations still using even one XP box could let someone into their infra. Also this means POSReady 2009 (also “XP”), which just lost support, gets patched on tens of thousands of POS terminals still in use for retail/banking.
