Windows 10 1803 | .NET Framework 3.5 installation error: 0x800F081F

Hi guys

Windows 10 gets more interesting day after day. I feel like Microsoft is slowly helping my HUGE beasty desktop machines to start looking like a MOBILE PHONE, well enough said.

One of the latest issues with Windows 10 version 1803 (build: 17134.81) is, one cannot add the .NET Framework 3.5 feature using “Turn Windows features…”, the attempts start reporting you are not connected to internet, which is not true (Microsoft should grow up)

So if you are looking for a quick solution to the said, don’t worry, Microsoft has truly messed up documentations available here:

https://support.microsoft.com/en-us/help/2734782/net-framework-3-5-installation-error-0x800f0906-0x800f081f-0x800f0907

& you should read this one as well

https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-8.1-and-8/hh825020(v=win.10)

Or if you don’t want to get confused, follow the instructions below:

Using the Windows Media Creation Tool for Version 1803, create ISO and mount it

Browse to sources\sxs folder within the ISO that’s been already mounted. Example, my ISO file is mounted on J: drive, hence the path to sources files is “J:\sources\sxs”

Copy the path and with an administrator account, open “LOCAL” group policy editor

Click Computer Configuration, click Administrative Templates, click System, and then double-click the Specify settings for optional component installation and component repair setting.

and once the LOCAL policies are updated, you have to apply it. Apply the policy changes using “gpupdate /force”. Don’t worry about domain policies (if you are using a domain joined computer)

Now try to install “.NET Framework 3.5”, should complete without giving more errors.

Hope this helps few out there
