The Windows XP SP4 Unofficial installer is dedicated to Windows XP users who are not able, cannot afford or do not want to migrate to a newer Windows edition. Please be advised that this package is not released by Microsoft, who does not recommend computer users to install it. The package is compatible with 32-bit versions of Windows XP, with SP1 installed and it can be deployed on an installation media.
