Before the High Sierra update, when I used to boot my Macbook Air, the keyboard backlight was always off by default. However, after the update, upon booting the backlight is always on. This is irksome because I always work in a well-lit environment and don't need the backlight. So I have to turn it off each time after start-up. I can't find out how to change this default setting. Can someone help?

Go to your system preferences (not sure if that's the exact name in English version of MacOS as I'm looking at the Dutch translation) > keyboard > disable "adjust keyboard backlight in low light environment" (or English words to that effect, it is next to a checkbox).
