Your rating: not submitted

Microsoft had officially ended the support for the Windows XP operating system and doesn't provide system updates any more. There still are many users without the possibility to upgrade their old computers to a newer system, so they won't be able to keep their OSs up-to-date anymore. A single convenient package containing all the Windows updates would be a suitable solution for them. The Windows XP Service Pack 4 Unofficial tries to solve this problem.

Windows XP Unofficial SP4 ENU is an update roll-up for Microsoft Windows XP which includes the latest system components and hotfixes. The package can be easily integrated with any Windows XP installation disk and includes the .NET Framework, versions 1.1, 3.5 and 4.0.


  • It's a good solution for users who are still using Windows XP.
  • It's simple and efficient.


  • Supports only the English language.
  • The update is not official and is not digitally signed by Microsoft.
