An unofficial Service Pack 4 for Windows XP
As you know, Windows XP support from Microsoft ended in April, with the result that the operating system is left without protection, and new security updates. Partly, you can extend support for some time simple but informal way, offering one enthusiast from Greece. More specifically, he has prepared an unofficial service pack for the 13-year-old operating system.
The project, which contains all the official updates from Microsoft, called Unofficial Service Pack 4 and work on it began in September 2013.
Unofficial SP4, which is currently available as a third beta, to be completed in the near future. The developer believes that many users are unable to upgrade older computers to the newer Windows versions, so he began work on this service pack, which will allow people to have access to all necessary updates. SP4 can be applied to any computer running Windows XP SP1 and above.
One of the places from where you can download an unofficial package, Softpedia is a site where in the description says that the SP4 are not made by Microsoft. The service pack contains updates for most Windows XP components, including MCE and Tablet PC.
