Nowadays I’d say driver discovery for virtually any modern hardware you might plug into your computer. You don’t even need to visit websites to download installers anymore. Literally plug it in and it will grab whatever is needed for it to work properly. Yes even Nvidia display driver. Even VR headset.

Never had any issues with multi-monitor setups out of the box either. It just works.

I’d also mention disposable Sandbox and virtualization in general. WSL also runs at native speeds.
