New submitter intensivevocoder shares an account by TechRepublic: Extended service for Windows Embedded POSReady 2009 — the last supported version of Windows based on Windows XP — ended on April 9, 2019, marking the last conclusion of this Windows NT 5.1 product lineup following 17 decades, 7 months, and 16 days. Counting this variant, Windows XP is your longest-lived version of Windows ever — a listing that’s not likely to be beaten. Regardless of the minimal end of support for Windows XP the existence of POSReady 2009 allowed users to receive security upgrades through the use of a hack on Windows XP Home and Professional SP3. Microsoft dissuaded users from doing this, saying that they”don’t fully protect Windows XP clients,” though no attempt was apparently made to prevent users from using this hack. The flow of those security updates will likewise come to an end, Together with POSReady reaching the end of service.
