It isn't clear to me either.
Boot Camp Assistant - save the drivers to USB etc (partition also, and start the install)
After Windows is installed either stop from doing more Windows updates or wait until done, is up to you.
THEN take the USB and run setup for Apple drivers.
Some devices like autio have to get Cirrus (or RealTek) AFTER installing Apple drivers.
I find "boot camp" to be used and over used to refer to too many things.
Windows on Mac
Drivers
partition tool
download apple drivers
control panel in Windows to change default OS, brightness and other items
you run Windows. natively.
hence, you really can't install software in Boot Camp.
You aren't running Boot Camp.
You have a number of Apple serivdes running in/under Windows though like Apple Timeservices, keyboard and others.
it is normal to have some devices and wifi/internet is a "sometimes" even with Apple driver.
In which you might try to locate and install those individually.
Whether it is best to allow Windows to do all its updates first, or interrupt and install Apple's, whether that even makes any difference....
You can always check in Programs control panel and repair-reinstal, or reinstall with admin or elevated privileges. Or compatibility mode.
I wish there were 4 subsections: mini have their own unique needs, iMac definitely and macbook like, and one for oothers (mac pro tower)
Or, that every Mac-Mini owner would add keyword "mini" and you can find the last 10 threads related to and posted by others. Should help.
