It is not from anything that I have installed. It is obviously from the PC vendor (HP, Dell), Microsoft Windows and Edge, anti-virus software, and maybe some others that I am not aware of. I have tried to turn off everything I can. It is annoying to have click off every option individually as there is no select all, and then click a back button and have everything turned on again by default and to have to turn everything off again individually.
After a while, certain notifications get turned on again without me having turned them on and without my permission.
