To create update media, start UpdateGenerator.exe:

Check off the products that you want to download the updates for. Also check if you want a ISO of the updates for each product, or if you are going to store the updates on a USB drive, check the box at the bottom labeled “Copy updates for selected products into directory”

Once the download is done (Anywhere from 15 minutes to 2+ hours, depending on your connection speed and products selected) copy this entire folder over to your USB drive. On the target machine that you want to update, run UpdateInstaller.exe and select any options that you want.
