What is a device driver?
A Device driver (or driver) is software that helps an operating system communicate with connected devices. In other words, device drivers are a set of files that are needed to operate or control hardware devices. Without a device driver, Windows OS is unable to recognize the type of device connected to it, and then you won’t be able to use that particular device. This is the reason why sometimes external devices do not work due to the corrupt, wrong, or missing drivers.
Where does Windows save or store device drivers?
The data that we have on Windows 11, Windows 10or other versions of Windows OS is stored in some specific location/folder on the hard drive. The same goes for device drivers. When Windows detects new devices, it finds and installs the compatible drivers for those devices, and stores their data in different folders. These folders are: You can access these folders using the following path: C:\Windows\System32
While the drivers folder contains SYS (.sys) files of installed drivers, the DriverStore folder includes a FileRepository sub-folder that contains INF (.inf) files of those drivers.
SYS files: SYS are system files of drivers required by Windows OS and these are commonly used to store drivers.INF files: On the other hand, an INF file is a text file that contains all the information that is required by Windows to install a device driver. This information file includes the name and the location of a particular driver, the version number of the driver, registry information, etc. That’s why the INF file is crucial for device installation. After opening the FileRepository folder, you will see the list of all drivers (in separate folders) installed on your system. The driver files that this folder contains are in INF format.
Before installing a driver, Windows copies the driver package to the DriverStore folder. This package contains the INF files and other files referred by the INF files. Some users download the device drivers from any website or untrusted sources. Downloading the drivers from untrusted sites can be a security threat because such files may contain a virus or malware. Hence, to protect users’ computers from such attacks, Windows verifies the integrity of the driver package by verifying the digital signatures before copying the driver package to the DriverStore folder.
