How can I turn off automatic personal hotspot activation when connecting an iPhone to a computer (Windows in this case)? I had it plugged in when downloading an iOS update and it downloaded the update over cellular data instead of home Wi-Fi.
I understand I can turn it off manually each time by going into settings, but how can I have it not turn on automatically so that I can only turn it on manually as desired to prevent accidental usage?

The problem isn't on your iPhone, it's on your Windows computer using the USB tether rather than Wi-Fi. You need to set the network interface priority on your Wi-Fi to be higher than the USB device, or the USB device to be lower, so that it will only use the tether if it isn't connected to Wi-Fi.
Make sure to connect the iPhone first. Directions for Windows 7 are here (these will likely work on newer versions as well):
Alternately, you could disable the connection on your Windows computer but you'll still have to manually turn it on each time so I think the above fix will provide the result you want.
