You're correct that it is not straight forward, but I am the OEM. I build my own computers from components since the 1980s. I've never had any problems with drivers. You see, my motherboard is an ASUS and the Radeon component is fully compatible with the ASUS motherboard. The driver for the Radeon has always been the originally installed AMD driver. It has always done its own update checks and updated without intrusion by Microsoft.
However, as a result of some Microsoft update, the OS manufacturer (guess who) began deleting the AMD drivers (yes, deleting them), and installing its own driver. It tells you that the Microsoft driver is all you need. It isn't. I had to go through a mammoth procedure with the help of AMD support to clean out all the Microsoft junk that wasn't working. I also had to change OS policies to allow the AMD driver to be installed, and change setting on the OS to prevent it from doing automatic updates of AMD Radeon software.
Sorry, but that is ALL on Microsoft. Just like they forever kept resetting my computer to shove Edge down my throat. Just like they blocked setting Google maps as the default maps handler. There are a ton of apps I have set as my default preferences. Unfortunately, they are not Microsoft. MS has removed perfectly good competitive 3d party applications from its app store. They've made it super difficult to select a non-MS app to handle a file from the Right Click (Open with) menu.
Any objective examination by an impartial party will confirm that Microsoft is illegally exercising its monopoly power in a highly anti-competitive manner. No doubt they filled some big lobby pockets to disable the enforcement of anti-trust laws. After their campaign to destroy Netscape and replace it with their inferior Internet Explorer, tightly bundling it with their OS, they lost the lawsuit. They were violating anti-trust laws. They are now as well, but they paved the way with legislation and party bribes. I am of the educated legal experience opinion that those laws should be again enforced and the MS anti-competitive monopoly should be stopped.
