Device Driver in Windows 7 tutorials

  • A device Drive is small Program written by hardware developers that allows hardware to communicate with particular operating system of computer.

  • Device Driver designed for 32 bit do not work with 64 bit Operating System and same way 64 bit drivers do not works for 32 bit.

  • Driver signing - when a device and driver pass Microsoft rigorous test in lab, Drive is digitally signed. Digital signature means that driver has met testing, it is stable, reliable and it is not altered after it is digitally signed. Signature file is stored as a .cat file in same location as the driver file.

  • Driver Store is a driver repository in Windows 7.

  • Windows drivers are stored at « systemroot\System32\DriverStore» folder.

  • During hardware installation if right drive is not found, Windows uses Windows Error Reporting to report an unknown device. You can usually find unknown device at Device Manager. Once you see any such unknown Device, you can then load drivers from different location.

  • Device metadata system provides process for defining and distributing device metadata packages. These packages include XML documents that specify properties of device and its function.

  • You can use Pnputil.exe tool to add driver manually.

 

Installing Device and Drivers

  • Since Windows 95, windows have supported Plug and Play devices and driver installation.

  • By plug and play means, device must contain driver and information to

  • get uniquely identified,

  • Identify the driver that supports it.

  • Allows software to install it,

  • Specify the services it provides and resources it requires,

  • To install driver successfully device must have drivers software with Windows, or Windows Update or User must have driver available in some media (CD, DVD, Pen Drive, network storage and so on).

  • When a user install a device, Windows detects it, and then ask the Plug and Play service to make that device operational.

  • Plug and Play queries the device and searches the driver store for a driver, if driver package is found, it copies the device driver files from the driver store to %systemroot%\windows32\drivers, and then updates the registry if needed.

  • If matching drivers are not found in the driver store, Windows searches for a matching driver by searching at

  • Folders specified by the Device Path registry entry.

  • The Windows Update website.

  • Manufacturer’s website that is provided after the system prompts the user.

  • Windows also checks that the driver has a valid digital signature. If digital signature certificate not found, Windows prompts the user for confirmation.
