Security Updates Errors (0x800f0983 0x800f081f 0x80070306)

[phmmuller]

I use a few VMs for work, also running Win 11 Pro, and on the ones where I used Win11Debloat, I've been getting errors like 0x800f0983, 0x800f081f, or 0x80070306.

For me, this started happening around Sep'25 (KB5065426) or Oct'25 (KB5066835).

I'm not one of those lunatics who disables everything; I just go with the default settings and maybe uninstall OneDrive, Xbox, Copilot... stuff I've never had issues with before.

Maybe Microsoft increased the dependency levels or requirements for installing these updates.

Is anyone else going through the same thing?

Heya,

I have not personally run into this, but I have seen quite some reports around those version with issues related to Windows Update. Have you tried Fix problems using Windows Update to do a repair install of Windows components? This is found under System > Recovery. It's mentioned here as a potential fix: https://learn.microsoft.com/en-us/answers/questions/5585524/failed-to-install-on-10-15-2025-0x800f0983))-2025

Yes, It does fix it..
Both the Recovery > Fix problems using Windows Update option and using a Windows ISO to reinstall while keeping your personal files and apps will solve the issue.
The downside is that changes made via Win11Debloat are undone as well.
