This was Windows 10, and it’s mostly drivers and utilities. I had a ton of trouble getting my wife’s mic working, which apparently needed some user space utility to be configured, and this was just a simple 3.5mm mic (AMD audio card apparently). And then there was random stuff in Device Manager that didn’t have drivers that I needed to track down (motherboard level stuff, not accessories). I spent like 30 minutes messing with a weird flickering issue (only happened in games), and it was solved by switching which monitor was primary (she apparently can’t use her 144hz monitor as primary, but whatever).
The actual Windows installation process was quick (she has an NVMe drive), it’s just all the nonsense afterward to get stuff running correctly. And that doesn’t include installing applications (she handled most of that, I hate tracking down SW on Windows), this is just to get the hardware to work properly.
On Linux, I just install the system, install packages from the package manager, and I’m done. No googling anything, no configuration, I just install the handful of packages I need that don’t come with the base system and I’m done. I had more trouble in the past (muted audio, Wi-Fi cards that need to be force enabled, etc), but the last time I had anything like that was something like 10 years ago. I do pick my hardware carefully which certainly helps, but surely Windows should provide a better experience since that’s what manufacturers target.
