driverstore

DriverStore is a centralized repository and catalog of driver packages used by the Windows operating system to install and manage hardware drivers. It is part of the system’s plug-and-play infrastructure and helps Windows supply appropriate drivers during device installation, updates, and offline deployments. The store is located in the Windows system directory, typically under C:\Windows\System32\DriverStore. Individual driver packages are stored in subfolders within FileRepository, with each package containing an INF file, a catalog file (.cat), and related driver files.

Purpose and function

The driver store serves as a single source of truth for driver packages that Windows may install for devices across the system. It enables driver installation without repeated downloads, supports driver updates, and provides a stable baseline for driver rollbacks if needed. The store also facilitates offline driver provisioning, such as when installing Windows on devices without immediate internet access.

Structure and contents

Driver packages in the store are organized in FileRepository. Each package represents a specific driver version for a device family and includes the necessary INF, catalog, and supporting files. The store is managed by system components and is accessed by the Plug and Play manager, Windows Update, and installation tools during device detection and driver installation.

Management and tools

Administrators can view and manage driver store contents using built-in tools such as the pnputil command-line utility (for listing, adding, deleting, or installing drivers) and the DISM tool for offline images. Third-party tools also exist to inventory and clean the driver store. Changes to the store should be performed with caution, as improper modifications can affect hardware functionality.

Security and integrity

Driver packages in the store are signed and validated to ensure integrity and compatibility. The store’s integrity is important for reliable hardware operation and system stability.
