Win 10 2004 Update Error 0x800f0900

[KwiatkowskiZFB]

Hello everyone,

I'm trying to install KB4576945 but everytime Windows Update hits the 0x800f0900 error.

Can anyone help me?


The DISM command threw the 0x800f081f error.

That is a patch for Net Framework 3.5 and 4.8 perhaps you don't have one or the other installed?

Here is 4.8 download:
Download .NET Framework 4.8 | Free official downloads
and 3.5:
Download .NET Framework 3.5 SP1 | Free official downloads

Thanks for your responses, but I already have installed both Frameworks.

I could install updates for .NET Framework 3.5 and 4.8 like KB4576478 and KB4569745 before.

Regards.

Did you try installing it using the Microsoft Catalog Standalone Installer?
Microsoft Update Catalog

Yes I tried it, but unfortunately it didn't work.
It ends with "The following updates were not installed: Update for Windows (KB4576945)"
