Funny enough, today I installed Killer drivers via Windows Update and the thing is working. My interface is good. All is nice. Still in 1809 tho.

I guess the only way to update windows for music machines is to install something like Acronis True Image and run a full backup before updating. If anything goes south, you can go back. I guess you can do the same with windows restore, but I have had several ocassions where a mesagge saying that it could not restore killed all.
