Resolve: Validation fails on genuine Windows 7 while installing Microsoft Updates

If while installing updates or files from the Microsoft Download Center, your validation for your Genuine Windows 7 fails and you receive this message: This copy of Windows is not Genuine!, which may also be accompanied with validation error code, 1699978131, 1571607440, 757834664 or 228668481! then this article may interest you.

The Non-genuine warnings occur when Multilingual User Interface packs are installed on incorrect editions of Windows 7!

Specifically, this issue could occur when you try to install Multilingual User Interface (MUI) packs on Windows 7 Starter, Home Basic, Home Premium, or Professional edition.

Multilingual User Interface (MUI) packs require a license to be used and are available only for Windows 7 Ultimate and Windows 7 Enterprise editions.

If these language files are present on another edition of Windows 7, genuine technologies will detect tampering on the system and display the non-genuine warnings.

To resolve this issue you will have to remove the MUIs or reinstall Windows 7.
