No, that person already had a PDF viewer installed, more capable than the one built in to edge. There is no excuse to replacing that on a forced update without notification. Seriously, you can explain anything this way: “all files deleted” alternative: “Microsoft just helping you free up space” or “the files weren’t backed up so they weren’t important”. Microsoft is squarely in the “monopolistic bad guy” corner here.
