windows 11 thunderbolt 4 bug
Hi, I got a new Dell XPS 15 9520 (12th gen i9) few months ago. When I connect a Thunderbolt audio Interface, nothing happens, like if the port was dead. I've look in device manager and I cannot find any Thunderbolt Controller. No Thunderbolt services was running and even Intel Driver and Support Assistant cannot find any Thunderbolt controller on my laptop. I've opened a ticket with Dell. They change the motherboard, change the controller, nothing is working. After some search about this issue, I find other people with similar issue with other brand laptop (hp, Asus, Lenovo) but always with a 12th gen Intel. I made a clean install with windows 10 and the Thunderbolt controller show up immediately (model 463e). Everything works fine on windows 10. Finally, I start an update to windows 11, build 22623.730 and my thunderbolt is gone again. On intel and Dell website, both report that there's no additional driver for thunderbolt with a 12th gen CPU and windows 11. Someone else are aware of this issue?

Projectik A couple of my machines transferred data at usb 2 speeds. There were no new drivers. I checked the BIOS and added support for thunderbolt. I now get usb 3 speed. The Thinkpad said I didn't need to add thunderbolt support unless I was using linux or win10 pre 17????? Thanks Microsoft, I can always depend on you to f... things up.
- ...same here on HP Studio G9
Projectik - I am experiencing the same issue on latest Windows 11.

I have had the motherboard replaced, tried a handful of drivers (Windows 10 drivers from Lenovo, Intel NUC driver package, http://www.catalog.update.microsoft.com) all of varying version numbers and via various methods (running the exe package, manual install via device manager). I just finished performing a factory restore from a USB Lenovo sent me, and am checking Device Manager before every update. Haven't been able to get the Thunderbolt controller to show up in Device Manager.
- I have a repair ticket opened with Lenova. I believe I will pass on the motherboard replacement, since I now firmly believe the problem is with Windows 11. They have sold a lot of new laptops with Thunderbolt 4 capabilities that aren't working, which they should make right on. Who is to blame? Most of the machines are in the $3000.00 and up price ranges.
- Same here. Lenovo slim 7i pro x
i7-12700H, there's no thunderbolt controller on Windows 11- I had to do a power drain which made my Thunderbolt working again 🤦:male_sign:🤦:male_sign:🤦:male_sign: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Laptops/Yoga-Slim-7i-Pro-X14-Thunderbolt-4-stopped-working-after-updates/m-p/5194535
- I think it's hardware related. I'm in windows11 beta channel, and i installed every single update but both thunderbolt ports works fine.
- I have an Windows11 Alienware laptop (12 gen i7) and starting just a few days ago, my egpu setup is no longer working. It blue screens when I try to plug in my Razor egpu and I also don't see the Thunderbolt Controller in my Device manager any longer. This worked fine just a few weeks ago!
Okay, so my issue turned out to be a bit different after all... It appeared to be due to driver miss-match. Here is the solution for my specific problem--https://mysupport.razer.com/app/answers/detail/a_id/5870/kw/Core%20X%20Chroma
By showing hidden devices under Device Manager when disconnected from the internet, I was able to find the hidden device and remove the driver causing the issue.
- Same here, seems that in Windows 11 the ports works as USB4 only, it's so weird 😕 plis if you find a solution let us know.
