Linux has made leaps and bounds with usability and ease of installation but it’s no better than any other modern OS - which is a good thing. Installing Windows from a USB stick is not difficult - the simple path is literally, pick a language, select your wifi, choose who is logging in, click install and go grab a coffee. About the only difficulty if you can call it one is that some installs will ask for a serial number because it’s a commercial product.
Also, the number of questions & buttons during installation is one thing but the certainty of a functioning system is another. Linux is better at supporting old hardware, Windows is better at supporting new hardware. Choose accordingly if that matters.
And downloading updates is a good thing. Means that the fresh installation isn’t vulnerable to something that was fixed between when the USB / DVD was pressed and the time the person installed it.
