On my NUC8i7BEH, it is impossible to install DCH drivers concerning gfx graphics driver (I have download them on the intel web site according to the model number). Windows 10 pro (up to date in 1903) tells me that it is a non certified driver !

Windows has found a driver during installation but I'm not sure that it is the same. I tried to install intel driver assistant but it fails during initializing installation of the software !!

1. Disconnect the Internet. Please open Apps and Features (in Windows Settings).
2. Locate in the Application list the Intel Graphics Driver. Click on it and then click on Uninstall.
3. Once the driver is uninstalled, reboot your NUC.
4. Install the previously downloaded DCH driver.
5. Reconnect the internet and reboot NUC.
6. BTW, the latest Windows 10 version is 1909, rather than 1903. So, if you have still version 1903, better update it.

I have found on the web that the graphics driver installed by windows update block the installation of the normal dch drivers downloaded from intel web site. So I think that your solution is ok ok with this fact ? isnt'it

That is correct. The legacy driver blocks the DCH driver installation. So, the first time the DCH driver is installed the legacy driver should be removed.
