Failure updating Thunderbolt 3 DCH Driver

[wamaruna]

The Intel Driver and Support Assistant keeps telling me to install the update for Thunderbolt™ 3 DCH Driver for Windows® 10 for Intel® NUC. My NUC model is NUC10i7FNH1.  But every time I try to run it, I get the message that it failed.  No other info.  Can you help to resolve?

Had the same on my NUC10i7FNB
This is probably because no Thunderbolt device is connected

Download TBT-Win10-1.41.1054.0.zip
Navigate to the INF folder, right-click on the two .inf files shown below, and select Install.
-TbtHostController.inf
-TbtHostControllerExtension.inf
Reboot

The DCH drivers are a pain in the derriere, Thunderbolt particularly.

You must download the drivers manually and unzip the contents. Then you must uninstall the Thunderbolt software in the Windows apps list. Then you must check in Device Mangler that the drivers also uninstalled and that you have a Base Device (if not, you can scroll through System Devices to find the Thunderbolt controller and uninstall it there, which will create this Base Device). Right click on the Base Device and select to Update Drivers. Point this to the folder where you unzipped the driver package and let it run. Finally, you must reinstall the Thunderbolt software from Microsoft Store.

The links for all this are on the page where you manually download the driver.

The real annoyance for me is that, despite doing all this with the latest (2020-12-02) driver and confirming in Device Manager that the driver matches the version and date, DSA _still_ tells me that I need to update the driver. My Thunderbolt is running smoothly but DSA thinks it's out-of-date.
