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.
You know what? Windows doesn't get enough credit for its multimonitor window management. Win11 saving window combos and providing easy partitioning and docking on each monitor is actually really cool, and the keyboard shortcuts to handle them are simple and useful. There are lots of things about it I don't like (I'll keep whining for a movable taskbar until I get one back, Microsoft), but I'll admit they do that well.
I honestly doubt that WSL runs at native speeds. WSL2 literally runs in a VM, and IO performance is known to be worse even compared to WSL1. Maybe it's just not directly noticable. Do you run a graphical environment in it? If not, that could help a lot too in not noticing it.
Nah I don't run anything related to graphics. Mainly clang compiler. Speaking of native speeds I mentioned, sysbench gives me pretty much the same results in WSL and in native Linux, with a margin of error here and there.
