Install Error for KB5033375 - Error Code 0x800f081f

Question

I have unable to install this update KB5033375. I receive the code 0x800f081f - Install Error.

I have attempted to install the KB directly from the Update Catalog from MS, same error.

Tried DISM tool and SFC - neither found issues.

I have disabled my AV (Sophos).

I cannot afford to do the in place refresh which will cause me to lose all the production applications I need to support my company.

Does anyone have some input?

I am currently on Win11 22H2.

Answer 1

I have the same problem.

Fresh installed Windows 11 23H2 from 2 weeks ago!

This is just incredible that a Windows installation not even 2 weeks old is already failing an update.

I tried everything.

1.) Windows Update Troubleshooter

2.) BITS troubleshooter

3.) Reset of Windows Update Cache

4.) SFC

5.) DISM

Nothing helped.

According to the internet the only thing which will help is an inplace upgrade.

I am also not willing to do this as it will mess up my highly customized system.

I will wait another few weeks. Maybe someone will come up with a solution.

Worst case I will have to reinstall my system which will take me another 2 days until everything is installed and customized again.

The crazy thing is that I have an identical second install on the same computer with the exact same settings and drivers except the installed programs are different. This system updated just fine. Nobody can explain this with reason.

Let's hope for the best in the coming weeks that someone will come up with a reasonable solution.
