How to install 20H2 when WU is having problems

Six computers ranging from 10+ to 2 years old or so. One of the newer computer has now failed to install the October cumulative update multiple times a day for almost a month. No idea why. First major issue I can recall. Everything I have tried to fix these errors has not worked. Manual installation failed as well which is doubly concerning. WU is working to a point since Defender definition are updating. But other updates (.NET update) have failed.

An in-place upgrade has been suggested to resolve the issue and since 20H2 is available.. My concern is will it even install? Normally I would do it via WU but it hasn't been offered and I am thinking because of the issue it may not as my other computers have been offered it. I will attempt to install it via MCT and USB. Any thoughts? Very concerned as to why I suddenly have an issue with this computer updating and if it can be resolved.

Use Windows Update Troubleshooter.

• Right-click on Start button and pick Settings
• Go to Update & Security > Troubleshoot
• Click on Windows Update and select Run the troubleshooter

Download Windows updates manually.

• Go to the official Microsoft update catalog;
• Enter a specific update code, for example, KB4481031
• Select the correct version and click Download
• Click on the link and Windows will update your computer

Resetting the Windows Update components can usually solve these types of issues.

As mentioned, I have done that. Ran troubleshooters, sfc, DISM, tried to install manually. No success.

I did this and it didn't help. I can try yours but your codes is all running together.

I would try upgrading again "manually"...meaning download the 20H2 ISO, right-click on the ISO and select Mount, double-click on setup.exe

There is a step at the beginning of the install process where you can tell the installer not to download updates at this time.

Select that.





If it fails, download and run SetupDiag -

Post the results.

Restart the PC & try updating again.

Ran it. Looks like it couldn't find the .bak folders to rename them. I didn't see a WindowsUpdate folder in the regedit.

WU immediately failed again with 0x80070157 for the KB4580419 .NET update and KB4579311 is again trying to install, and I am sure it will fail once I restart (which takes like 30 minutes each time).
