    One of the best possible alternatives to Adobe Reader and Foxit. FOSS, available as UWP. Isn't as lightweight as SumatraPDF, but has configurable memory/RAM profiles and a plenty of annotation options. Customizable and Privacy-respecting. What else do y'want? Except if you're searching for Booklet Printing or some Pro Features you get on other PDF apps, Okular is the pefect app.
