windows 11 thunderbolt 4 bug

I know this thread is quite old and we are now in 2024 but I have a Dell Inspiron 14 5430 with Thunderbolt 4 however Windows 11 is only picking up the TypeC Port as USB4.

In the Thunderbolt Control Center v1.0.37.0 it is showing the Controller Driver Version N/A

The app was installed from Factory.

I do not believe all the hundreds of users using Windows 11 with this problem have a hardware issue with their laptop, it seems more like Windows is not detecting correctly the Port and treating it as a standard USB4 Port.

I have installed the Intel Thunderbold 4 Controller drivers for my device and it does absolutely nothing.

In Universal Serial Bus Controllers in Device Manager I have the following:

"USB4(TM) Host Router (Microsoft)"

This device carries a Hardware ID of "A73E" (In device properties, details, hardware ID in the drop down menu) which identifies on a quick internet search as an "Intel Thunderbolt Controller"

The problem is I cannot install the Intel Thunderbolt Controller driver manually, Windows simply won't let me.

I think Microsoft need to acknowledge and fix the problem so that the correct drivers can be installed for the correct device. Without the Intel Thunderbolt Controller drivers being installed the Thunderbolt Control Center does not pick up any Thinderbolt connected devices because it does not see a controller.

If anyone with the issue is still around you may also probably see "USB4(TM) Host Router (Microsoft)" in USB Controllers in Device Manager. Check the Hardware ID in the properties and do a quick search and this is likely your Thunderbolt Controller incorrectly identified by Windows.
