Thunderbolt Software and Drivers

[tbuser17]

Hello - I am reaching out as I am unable to find the Intel Thunderbolt software that is compatible with my HP Spectre x360 15-bl112dx (product number Z4Z38UA#ABA). Briefly, external GPU connected through the thunderbolt port stopped working after a windows update. I am on Windows 10 1909. There are no hardware issues with the thunderbolt port on the basis of testing and it charges with no issue but the GPU and other ports are not recognized. In the setting of trying to rectify this issue, I have updated to the latest drivers on product page (the latest thunderbolt driver was from 2017) and I tried to re-install the thunderbolt software but this is not included on the product page. In addition, I tried to use the thunderbolt software available on the Windows Store, but the driver available on the HP website is incompatible with it due to not being DCH compatible.

On this basis, I had the following questions:

1) Is the Intel Thunderbolt Software available for download for my computer and can a link be shared (not the driver as I did download that)?

2) Is there a newer driver available that is DCH compatible with my computer such that I could download the software from the Windows Store?

Thank you very much for your assistance!

Hi Praveen,

Unfortunately the software (and associated instructions) from intel do not work. The download you directed me to is for a driver rather than the software (the instructions include downloading the thunderbolt controller from the microsoft store, which I am unable to do with the HP supplied driver). How can I recover the software that originally came with the computer or a more updated version?

Thank you.

Thank you for the update.

In that case, you have to perform the recovery using F11.

Performing the recovery you will lose the personal data and installed application.

Have a nice day!!
