Windows 10 update fails to download - 0x80244022
Go into “C:\Windows\SoftwareDistribution\Download” and delete everything in that folder.
Now, run the command prompt as an administrator. Type in “wuauclt.exe /updatenow”.
Reboot
Go to your Control Panel > Windows Update and your Windows 10 should start re-downloading from scratch, hopefully without flaws this time.
