I don't know. The first program scans for something. It must be even more serious than the bindings within File Explorer, because it reported to me it found nothing but, as per the MicroSoft tech's instructions, I then ran the second program and, voila, the system was restored and operating normally---just like doing a system restore with a restore point (with the exception that no recent data appeared to be lost or recent drivers removed). I persued this approach with MicroSoft because using restore and restore points didn't work for me. I asked them about the System Repair feature that used to be on Windows OS discs, which I couldn't find under Windows10.
