Method 1:

Clear Windows update temp files:

Run the following commands, and press Enter after each command:
Net stop wuauserv
cd %systemroot%
Ren SoftwareDistribution SoftwareDistribution.old
Net start wuauserv

Method 2:

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.
