I right clicked the rightmost icon in the task bar, then chose {Focus Assist > Alarms Only}. After I did that, the only times I have been notified on Windows is because I set a timer in the {Alarms & Clocks} app.
(I would probably have noticed any other notifications because I am sensitive enough to being notified that I completely disabled Notification Center on my Mac.)
