Microsoft has released a support bulletin that warns users of a new issue in Windows 10 that could cause Thunderbolt devices to stop working under certain situations.
According to the bulletin, this issue is occurring to users running Windows 10, version 1909, 1903, 1809, 1803, or 1709, have Fast Startup enabled, and have multiple devices plugged into a Thunderbolt dock.
If these users perform the following steps, it could cause the Thunderbolt devices to no longer work even though they are still listed as operational in Device Manager.
A Soft Off (S5) power state is entered when Windows fully shuts down, but the device continues to stay powered on. This power state is most commonly seen during a restart of Windows.
"The soft off state is when the system fully shuts down without a hibernation file. Soft off is also known as a "full shutdown." During a full shutdown and boot, the entire user session is torn down and restarted on the next boot. Consequently, a boot/startup from this state takes significantly longer than S1-S4. A full shutdown (S5) occurs when a system restart is requested (or an application calls a shutdown API)."
This issue only happens under certain circumstances and even then, only has a 5% failure rate, so it should not affect that many people.
If you do use a Thunderbolt dock with Windows 10 and find that your devices stop working, Microsoft states that you just need to restart your computer to get them working again.
When the failure occurs, the functionality of the devices cannot be restored by re-attaching the Thunderbolt Dock. Instead, you have to restart the computer.
To prevent this from happening, users of Thunderbolt docks can perform a full shutdown so that the PC is fully powered off and then power the device back on to start Windows.

Thunderbolt has so much small print in the margins, it doesn’t surprise me.
So it shouldn't happen often, right?
Because Windows computers rarely need to reboot.
Just for Windows Updates, or when problems happen, or the thing loses its mind.
:-)
I haven't had occasion to use it except on Macs, so far. Have you used it on Windows?
Compatibility and speed is very good, but you have to be very specific and careful when buying cables that convert from Display port/ hdmi / splits. The specs on devices need to be be studied before buying. I’ve still not found any bargains after comparing all relevant features.
