I wanted to play a silly Game and it demanded SP3 so I picked up this method instead of upgrading my OS just for a game. This is a quick hack to fake an upgrade from SP2 to SP3 on a running Windows XP. This will not actually make your OS equivalent to Sp3 releases.



Easy steps:

1. Open windows registry editor. ( Start > Run > regedit )
2. Take a backup of your current settings by going to File > Export
3. Now navigate to following registry key - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows
4. Now change the value of CSDVersion option, available in right, from 200 to 300

I know there are still many XP users left, hope this is useful to a few of them.
