Back when I used Windows I prided myself in my install age. Can't remember if I started on XP but at least made it from 7, 8, 8.1, to 10 over many years, repairing issues as they came up. DISM largely does the same thing as reinstall without nuking all your files/settings assuming you can get it pointed at a valid source if winsxs doesn't have the thing it needs.
