Known issues with this security update

The Windows Search update package is produced in English only. Although the update installs on other languages, there may be instances where the installer package shows both English and the language that is used by the localized operating system. This is expected behavior and occurs is because the installer package resources are taken both from the localized operating system and from the English update package. The package does address the security that is issue described in MS09-023, regardless of the language of the operating system.
