This post is more or less a note for myself and therefor I will not go into detail with this post. Next to this there are already many more posts about this subject if you would like to know more.

Step 1.

Copy the ‘sxs’ folder or at least the file: ‘microsoft-windows-netfx3-ondemand-package.cab’ to a folder from where you are going to install .net 3.5. This file folder can be found under ‘X:\Sources\’ in your extracted Windows 10 ISO.

Step 2.

Run the following command in a command prompt with elevated priviligers.

Replace ‘X:\’ with your source location.

Or the PowerShell command:

Replace ‘X:\’ with your source location.

The installation will start immediately.
