You can’t simply install the updates -- that would be too easy -- and you’ll receive a version mismatch error if you try. But a simple registry tweak is enough to fix that.
Create a text document, and call it XP.reg. You’ll need to make sure .reg is the proper extension -- so not "XP.reg.txt". If it’s not showing up as a registry file, open any folder, go to Tools > Folder Options, select View and uncheck 'Show hidden files and folders'. That should fix the problem.
Right-click the file, and select Edit. Paste in the following:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\WPA\PosReady]
"Installed"=dword:00000001
Save it, and then double-click the file. That will make that change to the registry. That’s all you need to do. Windows will now automatically fetch updates designed for POSReady 2009, ensuring XP remains protected for the foreseeable future.
This trick only works for 32-bit editions of XP, but there’s a workaround for 64-bit versions
