1. Go into "C:\Windows\SoftwareDistribution\Download" and delete everything in that folder.
2. Now, run the command prompt as an administrator. Type in "wuauclt.exe /updatenow".
3. Go to your Control Panel > Windows Update and your Windows 10 should start re-downloading from scratch, hopefully without flaws this time.
I finally have my update!!!!!!
I had to manually run the Windows 10 Compatibility Appraiser because the monthly one that happened on July 2 was when I had no space, but I cleaned up since then. If you aren't compatible it won't let you update.
