Windows XP itself no longer has any official updates. Some of the various security addons such as the Malicious Software Removal Tool still seem to get updates. But POSReady 2009, which is based on XP SP3, is still scheduled to receive updates until 2019, and there has been a trick discovered that allows your XP installation to appear to be POSReady 2009 to Windows Update, so the POSReady 2009 updates can be downloaded and installed to your XP installation. Does that answer your question? Cheers and Regards
