While we try to provide the best possible experience, it is important to clarify that Windows Update Restored is not perfect, and users may encounter certain known issues. Below are outlined ongoing challenges associated with each version, along with specific caveats:

Windows Update Restored V2

• Download Issues: Some updates may not download due to missing files (CIFs/packages).
• Driver Updates: Currently, driver updates may not show any available updates.
• Multilanguage Support: We are missing many inventories necessary for multi-language support, which might result in a "Cannot Display Page" message when checking for updates.

Windows Update Restored V3.1

• ActiveX Installation Conflicts: For Windows 98 First Edition, Second Edition, Windows Millennium Edition (Windows ME), and Windows 2000 systems, installing Windows Update v4 ActiveX Controls will disable the use of Windows Update v3.1.
• Windows 2000 Compatibility: Checking for updates does not work on Windows 2000 with Internet Explorer 6, as we are missing required inventories. This will lead to an error during the update process.
• Multilanguage Support: We are missing many inventories for multi-language support, which might trigger "Cannot Display Page" notifications.
• Driver Updates: Driver updates may not show any updates, and certain updates may not download due to missing files (CIFs/packages).

• Driver Updates: At this time, driver updates do not display any available updates across all supported operating systems.
• Multilanguage Support: Checking for updates on Windows 98 or Windows Millennium Edition in languages other than English or French may not display many available updates. We are actively working on adding more multilingual support.
• Windows Update Catalog: Not all the Windows Update Catalog has been translated, contributing to limited availability of updates.
