The biggest issue is when I have a computer with both integrated graphics, and a dedicated graphics card. I used to disable integrated graphics in the BIOS, but this causes a litany of problems now. Even with integrated disabled, Windows 10 will still try and install the drivers for it, and every time it does this, they seem to take precedence over my dedicated drivers. I ended up giving up and just enabling integrated and leaving the drivers there.
Also (having spent the day reinstalling a new Dell 2-in-1 with a clean Windows install) a few of the devices were quite happy (if generic) in Device Manager but didn't work quite right until I manually installed the drivers off the Dell website. (The ones that spring to mind were the wifi, audio drivers and the webcam, but there might have been others.)
cortana just yells at you until you can turn it off, you have to deselect every invasive feature and then get to some windows sign into your ms account bullshit
just.... why... since when did installing operating systems turn into avoiding landmines
linux and mac install pretty quick, but windows? fuck off
I clean-installed Win10 recently. There was no driver installation I had to do - everything works great, and there are no unidentified devices in Device Manager. Say what you will about Windows 10, but that part is really cool. Save for video cards, the pack-in drivers are often better and less hassle. Plus they auto update.
