Earlier this year in April Microsoft ended its support for Windows XP. So that meant no more security updates and fixes. Even though support for Windows XP has ended it is still a very popular operation system, especially in business and on ATM and other point-of-sale machines. Because of this the Windows community is working on updating XP and even has plans for an official service pack 4.
The unofficial service pack for Windows XP will be developed by Ryan VanderMeulen who has a long track record of releasing fixes for Windows operating systems. The unofficial service pack includes quite a few updates including updates for POSReady 2009, which is an embedded version of Windows XP.
“Windows XP Unofficial SP4 is a cumulative update rollup for Windows XP (x86). It can be applied to a live Windows XP system which has SP1, at minimum, installed or it can be slipstreamed (integrated) in any Windows XP installation media,” the developer says in the description of its pack….It includes updates for most Windows XP components, including MCE and Tablet PC. Request-only hotfixes have been included. Currently, Microsoft .NET Frameworks 4.0, 3.5, 1.1 and 1.0 (Tablet PC only) are included in the Windows XP SP4 package. You can also scan for POSReady updates, because the POSReady trick has been included. In addition, all post-eol updates for .NET Framework 1.1, 3.5 and 4.0 until May 2014 have been included.” States the developer Ryan VanderMeulen.
This project is nothing new, it has been in the works since late 2013, but only now has started to gain popularity since Microsoft ended support for Windows XP back in April. Unofficial patches have been rolled out in May, June, July and August so far. The unofficial service pack 4 can be downloaded here.
