ok weird one okay, help me do this properly. my home-built PC has the control panel won't open after a NVIDIA update and I've decided to go back to the previous driver.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
Ive downloaded DDU and teh older package. What exactly do I do, in what order, and how do I stop Windows from reinstalling the new one behind my back? I have never used DDU before, so please assume I know nothing. I do have a USB stick and a second device to read instructions on while I work.
