What is this .cab file?
In Windows, language support is split into several packages to save disk space. While a standard language pack provides the user interface (UI) text, the "LanguageFeatures-Basic" package provides the underlying logic for text input and processing. The unique identifier 31bf3856ad364e35 is a standard public key token used by Microsoft for signing official system packages, while amd64 indicates it is designed for 64-bit hardware architectures. When do you need to install it manually?
Most users receive this package automatically through Windows Update when adding a new language in Windows Settings. However, manual installation of the .cab file is often necessary in the following scenarios:
You are building a custom Windows image for enterprise deployment using DISM (Deployment Imaging Servicing and Management). You want all users to have the ability to type Chinese Simplified without downloading from Windows Update. You add this .cab to the image offline. If you install Simplified Chinese through Windows Settings
This CAB is the offline package for Windows’ basic Simplified Chinese language features for 64-bit systems. Use DISM or Windows deployment tools to add it to images or offline systems, ensure build/architecture compatibility, and prefer official Microsoft sources.
