How to Extend Windows XP Update

I read an article yesterday which describes how and why the Windows XP/2003 update period can be extended by doing a simple registry hack. It appears that the modification from Windows Registry makes the Windows appear as Windows Embedded POSReady 2009.

So, the idea is that the following registry key has to look as below:

[HKEY_LOCAL_MACHINE\SYSTEM\WPA\PosReady] 
“Installed”=dword:00000001

Great stuff, huh?! :-O OK, the good part is that Windows Embedded POSReady 2009 receives updates until April 2019. At least, that’s what the article says.
