Windows 10: Unable to complete the Feature Update to Windows 10, Version 1909

Tried to run the update twice today. Both times, I get the same message saying it was unable to update something. The update history shows:



Feature update to Windows 10, version 1909 2

Last failed install attempt on ‎9/‎10/‎2020 - 0xc1900101



The history shows failed attempts in August, July and June as well.


It shows a successful install of 1809:


Feature update to Windows 10, version 1809

Successfully installed on ‎2/‎13/‎2019



Any thoughts on what I should be doing differently?

Completely missing Dot Net in Windows 10 -1909?

.NET Framework is built-into Windows 10 version 1903 and Windows 10 version 1909. It is not possible for at least this version of the .NET Framework to be installed.

The error you have received, is likely due to the fact the application you are attempting to use, is specifically trying to target a version of the .NET Framework you don't have installed. I suggest using official Microsoft tool to download a Windows 10 version 1909 ISO. You can use the Media Creation Tool and/or the Upgrade Assistant. Windows ISO Downloader was only recently updated to support .NET Framework 4.8 on November 8th 2019. If you were not using Version 8.22, and would like to still use the tool, you need to download that version.

RaymondCC .NET Detector looks at registry keys that are created when you install .NET Framework. It does not support the .NET Framework version that are included with Windows 8.0+

The built-in version of the .NET Framework for Windows 10 version 1903 was .NET Framework 4.8

.NET Framework 4.5+ has never been located in the list of Windows Features for any version of Windows. The lack of .NET Framework 3.5 is likely due to your WinSxS directory not containing it.

You can install .NET Framework 3.5 if you run the same command you ran, but provide a source, to the components you need.

This is due to the fact the .Net Framework 4.8 is already installed on Windows 10 version 1903 and Windows 10 version 1909. .NET Framework 4.8 is an in-place upgrade to .NET Framework 4.5

This normally only happens when you have moved vital folders like the user's profile to a non-standard location.

Your inability to install .NET Framework 3.5 is extremely easy to fix and likely the reason your unable to run the third-party application. Perform the following steps to solve that problem.

1. Download a Windows 10 version 1909 ISO
   
2. Mount the ISO within Windows 10
   
3. Run the following command, the command assumes, the drive letter assigned to the virtual mount is D:
   
   • DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs
     

Source: Deploy .NET Framework 3.5 by using Deployment Image Servicing and Management (DISM)

 

Windows 10 version 1909 feature update could not be installed

The update of features of Windows 10, version 1909 x64 the download begins to install stops at 58% which restarts to download again and never completes the installation.

 

Windows Update History shows both Feature Updates 1903 and 1909 installed

After I installed the Windows 10 Feature Update from 1903 to 1909 my Windows Update History shows

Feature Updates (2)

Feature Update to Windows 10, version 1909 (2)

Feature Update to Windows 10, version 1903

Looking in the About page it lists Version 1909 OS Build 18363.720

In the past when I've installed a Feature Update it only shows the new update. In other words in this case it would only show 1909. Since it shows 1903 also is my computer really upgraded to 1909? Also the (2) after the 1909 is something I don't understand.

I would appreciate any help on this.
