What does dch driver mean?

DCH was proposed by Microsoft, the full name is "Declarative Componentized Hardware supported apps", referred to as "DCH", which means "declarative componentized hardware supported applications" . The DCH driver is a driver package that installs and runs on Windows 10 versions based on the Universal Windows Platform (UWP). Microsoft has adopted the new DCH driver architecture starting with the Windows 10 October 10, 2018 update, calling it the "Universal Windows Driver."

DCH, the full name is Declarative Componentized Hardware supported apps, is a new driver installation package form launched by Microsoft on the universal Windows platform, which allows developers to provide only one driver package It can run on many different devices, including embedded systems and PCs. Starting from Windows 10 1709, Windows 10 supports the installation of this type of driver package. Users who use the DCH driver may find that the original graphics card driver management panel has become an independent Windows App in the App Store. It can be found here.

The DCH driver is mainly used for graphics card drivers. The graphics card cannot be used without a driver. The Intel graphics card DCH driver is a modular card driver in the new driver mode under the WIN10 system. It generally does not include additional functions such as a control interface. It is basically a pure driver. The control panel (if any) needs to be downloaded separately through the WIN10 app store. DCH is just a new form of driver deployment. Microsoft encourages manufacturers and users to use this form to provide/install device drivers. A typical DCH driver needs to include basic drivers, optional component packages and optional hardware support applications. The purpose of adopting this structure is to allow OEMs to easily add their own customized functions to the original driver provided by IHV without modifying the original driver.

What is the difference between DCH driver and standard driver?

While the basic core component files remain the same, the DCH driver is packaged differently than the previous (Standard) driver. According to Microsoft's requirements, the DCH driver only contains basic drivers, does not include any UI and utilities, and does not include OEM customized components. The driver control panel will no longer be provided with the driver, but you need to obtain UWP by visiting the Microsoft Store. version of the driver control panel, or automatically download and install through Windows Update.

Compared with standard drivers, DCH drivers are cleaner, and the same version of universal drivers can be used on different hardware devices that are also running Windows 10 systems.

Currently among computer hardware manufacturers, Intel's core graphics driver and Nvidia's independent graphics driver update mainly use the DCH version.

For the Intel core graphics driver, users can directly overwrite and install from the old version of the standard driver to the new version of the DCH driver; while for the Nvidia independent graphics driver, users cannot upgrade from the old version of the standard driver. The driver directly overwrites and installs the DCH driver upgraded to the new version.

Taking the Nvidia graphics card driver as an example, if you download and install a new version of the DCH driver on a machine that originally installed the standard driver, the following error will appear:
