I have a four-day Thanksgiving Day holiday. I downloaded and used Windows ISO Downloader tool to download Windows 10 build 1809 ISO to my hard disk. I tried to burn the ISO to a DVD+R but I kept on getting messages saying that the ISO file is too big for a DVD! I downloaded and used Windows 7 USB DVD Download Tool to create bootable USB drive after getting messages saying that the ISO file is too big for a DVD! I wish to do clean installation of Windows 10 build 1809 but keep my data files. I copied my data files to an HDD just in case. I put games that I got from Steam on another SSD. Any suggestions?
