As reported by Wayne Williams at Betanews and confirmed by us, a simple registry hack to a Windows XP system tricks Windows Update into providing updates for it.
Williams says that the hack, included just below, makes the system look like Windows Embedded POSReady 2009 which will continue to receive updated until 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
[HKEY_LOCAL_MACHINE\SYSTEM\WPA\PosReady]
"Installed"=dword:00000001
Run it by double-clicking in Windows Explorer. After this is done, if you run Windows Update, it will find several updates, as illustrated in this screen capture:
The screen capture is from our own tests, which appear to work. Notice that two of the displayed updates are for WEPOS (Windows Embedded Point of Service) and Windows POSReady 2009. The others are for Windows Server 2003, which runs the same kernel and many other components as Windows XP.
This specific hack works only on 32-bit systems, but a 64-bit workaround is available at this page, which may have been Williams's source for the 32-bit hack.
