Every update that's failed to install in the past two weeks on my computer with a new, fresh install of Windows 10 Version 1903 has failed to install with an error code of 0x80070003.
- 2019-10 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4517389) (five times)
- Update for Windows (KB4517389) (same as above only offline installer)
- 2019-10 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1903 for x64 (KB4524100) (three times)
In particular, even when only installing KB4517389, the update will only get to 7%, reboot, and immediately uninstall with no explanation why.
The troubleshooter completed "successfully," but did not help.
DISM and SFC found no problems.
Deleting the updates and re-acquiring them did not help.
So I'm kinda stuck. The Cumulative Updates keep attempting to install, downloading and restarting my computer periodically, and it's really annoying. I don't want to disable Windows Updates, which I know is an option. I want it to work.
