vostro 7500 thunderbolt quit working after windows update
I am using the thunderbolt port for a docking station. I have ethernet, 2 monitors and keyboard mouse. This is the second time this has happened to my since July. The last time it turned out to be that the Dell update that had the thunderbolt update didn't download due to a slow internet connection. Once I got a better connection it worked again. I tried updating every driver I could think of. Dell support assist says everything is up to date. I tried uninstalling the windows updates but removing the security update fails to complete. I uninstalled and reinstalled everything usb or thunderbolt or displayport related in device manager. restarted a dozen time. It does not to appear to be a dock issue (backup dock also gets no results), the thunderbolt port is just not working. laptop does not acknowledge and power via the connection (usually does). What else can I try?

My machine is not under warranty. This is almost certainly a software or firmware issue.

Hey,
having the same issues with 3 different vostro 7500 Laptops and more than 3 different Dell dock that were tested in the office.
After the update, it seems, 2 Laptops wouldn't connect any Dell Dock in the office. after letting them plug in and trying to update via windows update / dell nothing changes. We restarted one of the Laptops about 8 times and ups it worked it again. The second had the same pattern. Restarted it a couple of times and woop working again....
The 3rd one is a little nasty. Still not working. Up to date with alle drivers. in the hardware manager its just shown as "DockinStation" with nothing else. Looking into details it shows drivers from 2006 but i dont think that matters? was like that on the first two laptops and solved itself ...
still haven't figured out whats the issue and how to solve it.

Hi all, I have solved this issue by uninstalling and reinstalling drivers.
Step 1: Download dell command update.
Step 2: Stop windows from auto-installing drivers by following this guide: https://mostechtips.com/how-to-stop-windows-10-automatically-installing-drivers/
Step 3: Use this tool to force uninstall EVERY DRIVER except for nivida graphics drivers and intel graphics drivers. Make sure you tick the "force" box before uninstalling.
Step 4: Restart, run dell command update, and update drivers.
Step 4: I found that Dell Command update didn't get the audio drivers, so go to dell website and grab those. realtek audio whatever.
Step 5: test your thunderbolt port. Works fine.
There seems to have been a driver bundled with windows update that broke thunderbolt. No idea which one exactly it is, so the best method is delete them all. Then get your drivers from dell.

I forgot to mention the tool for nuking the drivers. It's this one: https://github.com/lostindark/DriverStoreExplorer
