As I understand Windows 10 Fall Creators Update includes .NET 4.7.1. It is possible to remove this .NET Framework version from this Windows 10 build? It looks like it is deeply integrated and can't be removed.
Based on Microsoft official information:
The .NET Framework 4.7.1 is included with:
Windows 10 Fall Creators Update (version 1709) Windows Server 2016 (version 1709)
It's as a windows component, you can't remove it.
