Upon installation, Wi-Fi drivers don’t exist, so you cannot use the internet while installing if you’re on Wi-Fi.
This is a good thing with modern Windows. You don't want it online while it's installing, you want to install, lock things down a bit and then connect.
Yeah I mean I downgrade new computers to Windows 10 Enterprise and ~~patch~~ authenticate with MAS. I tried using Windows 11, but the taskbar pissed me off too much - I want separate tabs starting from the left, not combined, and everything always showing in the notification area. I was going to put up with the tab thing but having to manually set every single notification icon to not hide itself away was just a dealbreaker. I want to know what's running, so I know to kill it.
