disconnect ur pc from power physically if the behavior continues which i would guess it will its probably something connected to ur wifi doing something in a dumb way if it stops thats wierd as fuck but forcing the pc to shut down by holding the power button should do the trick since that usually tells the motherboard to tell the power supply to shut off and i dont think windows gets a say on that.
the grass is roughly as green on the other side, android is no better for privacy unless u are willing to put in an unreasonable amount of work into it which isnt worth it for most peoples threat profile, i recommend switching passwords on everything and maybe factory resetting ur phone. Also u should switch but only because apple makes garbage products.
