//I was recently having some problems with iTunes, and decided to 
reinstall macOS Sierra. I held Command+R on startup and clicked on 
"Reinstall macOS" without erasing the hard drive in Disk Utility. Once 
the reinstall was complete, I started back up and all of my files and 
programs were still there, along with my settings, desktop wallpaper, 
and everything else. (The iTunes problems were fixed.)//

What exactly does this "Reinstall" feature do, if it doesn't remove 
programs and change settings to default?//
