Thank you very much for contacting the Intel® Communities Team, akrios.
Allow me to share with you that Intel® does not provide USB 3.0 drivers for 3rd party boards. If you have an Intel® Product such as a NUC or Intel® Compute Stick you can get the drivers from https://ark.intel.com/. For the Z370 chipset, you should be able to get the drivers from your mainboard manufacturer, if you are unable to find drivers for your system, please get in touch with the board manufacturer for you to get them.
Let me state this (more) clearly: Windows 10 has USB drivers built-in; there are no separate drivers provided by Intel or anyone else. Make sure that you have (a) installed the latest BIOS version available for your board and (b) installed the Intel Chipset Device Software (a.k.a. INF Update) package. The latter package optimally configures the USB drivers included in Windows 10. Download both of these items from your board manufacturer's site.
