My XPS 8930 will not run Windows 10 Pro included screen savers nor any other screen saver that run on my old Inspiron 3847 and XPS laptop. I've found nothing online that gives me a clue as to why screen savers do not work. Any assistance would be appreciated! (I know, screen savers are no longer necessary, but I happen to find them to be soothing.)
This page has a number of suggestions.
Non activated windows will not allow screen savers
