Same old, same old...
Since the days of Windows 95, upon booting the system checks/maps network drives BEFORE initialising the WiFi. The result is an error report/notification upon a reboot.
It isn't as if Microsoft haven't noticed this. I reported it as a tester on windows 95, NT4 and Windows 10. When the simple stuff is never done because the 'bells and whistles' to attract non-IT-savvy people/users has priority, we will for ever be plagued by bugs that never seem to be correctly prioritised.
Just saying...
