After this I can't open AMD Settings, when I launch this nothing happens, only that loading circle on cursor. Not even any process in task manager! All I found on forums and web, is unresolved threads, random fixes, drivers reinstall (I already told why I don't want to mess up with 'em), and complete Windows reinstall (I REALLY don't want to do that).
This wouldn't be so problem, but apps and games very often choose Intel Graphics instead of AMD.
(P. S. Personally I already tired of Lenovo and AMD, first won't update software, second won't make it stable)
Windows Update will only install the display drivers, it will not install other driver components like Radeon Settings.
As explained on the other thread, your system includes a legacy product with a currently supported product, so you can only rely on Windows Update for driver support.
