Yes, can confirm I was installing Win11 on my brother-in-law's new PC that I built last week and there were no default drivers for the USB wifi adapter I had attempted to reuse from his old machine. The entire process was roadblocked wanting me to plug into Ethernet until I researched the secret keyboard combination that allows you to shell out and then restart with the ability to do a network-free install.
I was using a Win 11 Pro installer stick on a Surface 4 the other day paired with a USB Ethernet interface. Aside from the fact that keyboard and mouse don’t work, because Windows doesn’t have drivers for a Microsoft Surface during install, I was able to convince Microsoft that I have no connection by unplugging the Ethernet cable right before the Microsoft account login prompt. Maybe I was lucky? Or really old installer? (Got it from Amazon Japan)
It’s definitely not an OS I would like to make my daily driver. I just hope Apple won’t go down that road with macOS.
