PS i found a way to install just the bare GPU drivers, without the gaming ballox, GPU audio and more; first uninstall (i used an AMD cleanup tool). Reboot and then manually select the appropriate driver via Device Manager, by locating it yourself. in my case i copied it first from C:\AMD\Packages\Drivers\Radeon-Adrenalin-18.5.1-c0328911-win10-64bit-180522_drvWHQL, an installer folder.

Important: You'll still have to disable the Atierecord registry entry after that. Seems stable now regarding audio stutter, and my graphics issues with the standard Microsoft drivers seems over. I did use an older driver in my case; my AMD GPU card is 4 years old now. -F
