My laptop has Windows 10 - 1909 version and I am trying to update it to 20H2 for months but it fails or gets stuck every time. Yesterday I even did COMPLETE WINDOWS RESET with Remove Everything - Erasure option- Remove files and Clean all Drives. Even after this when I tried to update to 20H2, it took almost 10 hours to reach '95% Installing' and now its stuck on that.And this is not first time I faced issues with Windows 10 update. Earlier I even tried with Windows Media Creation tool by downloading copy of 21H1, but it slowed down PC and games were running with a lot of lag. I had to uninsta

Updating Win 10 1909 to 20H2 directly, will there be any problems?

Hi Tinish

It is perfectly fine to update from version 1909 to version 20h2, no need to install version 2004, I just updated two of my laptops from 1909 and absolutely no problems on either, the update went smoothly on both

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

 

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
