Before using the upgrading assistant from the Microsoft's website, i have uninstalled the conexant drivers with the suppress option of the peripherals manager, and it works for me.
At least for now. Will see later.

My hardware is an ASUS UX305LA with Windows 10 64bits.
And no problems with these Conexant audio drivers reinstalled after the upgraded Windows 10, for now.

The windows reliability history does not show a single alert since the upgrade.
