2014年4月8日，微軟停止了對Windows XP的支持，不再向該系統提供熱修復、產品更新及安全補丁等服務。微軟多次表示，XP在無法獲取系統更新、安全補丁後極易受到攻擊，建議大家抓緊時間升級到新系統。

　　事實上，Windows XP仍然有辦法能獲得微軟發布的更新。有德國技術高手在論壇上發布了一則教程，對Windows XP做一些手腳，就能讓Windows Update服務器誤以為你的XP是Windows Embedded POSReady 2009，從而繼續為電腦提供Windows更新和安全補丁。

　　而現在，已經有高手將之做成了一個APP—— XP Update Extender，使用起來更加方便，而且效果與德國高手的教程一樣。

　　Windows Embedded POSReady 2009是基於XP Embedded Standard 2009官方搭建的版本，操作、使用和用戶體驗和普通版XP無異，但與Windows XP不同，Windows Embedded POSReady 2009的官方支持期限截至2019年4月9日。

不過畢竟 POS 系統跟一般使用者的系統還是有所差異,所以如果你想使用這個程式,更新前請做好備份.

XP Update Extender allows you to receive updates for Windows XP until 2019. Therefore all it does is to set a registry key pretending to be a version of XP Embedded
called 「POSReady「. It does not modify any system files.
Pretending to be running this particular version of Windows, you will receive updates made for exactly this version of Windows XP.
Those updates may not have been properly tested for your version of Windows XP and might harm your system. Use at your own risk!
Microsoft can prevent this 「hack」 any time.

These updates do not guarantee your systems' security, you should upgrade to a more modern system like Windows 8 as soon as possible!
