One of the most successful operating-system of all times - Microsoft Windows XP went "End-Of-Life" on April, 8th, 2014 leaving users with vulnerable systems as no updates including critical security-patches will get issued by Microsoft in future to "general" users. However, the company will be providing security patches to users enrolled under their "Windows Embedded POSReady 2009" program and below shared registry hack will let any "Windows XP" user receive the same patches for free till April 9, 2019.
To apply the hack, create a text file with a .reg extension and the contents below:
Windows Registry Editor Version 5.00
Merge the above registry code by double-clicking in Windows Explorer and then run Windows Update, which will find several updates confirming the successful activation of the hack.
