Updating Offline Windows 10 with NTLite and enabling .Net 3.5

For imaging I use an extracted .ISO of Windows 10 Enterprise, apply updates using WHDownloader and NTLite, and make settings changes.

One thing missing that needs to be included is the Feature .Net 3.5.  Without this, problems will most likely occur down the road.  This is not listed as an option in NTLite.
But there is an easy solution.  Click on the Updates page of NTLite.  Now browse to your extracted ISO of Windows 10. Specifically to \Sources\SXS

Drag the Microsoft-windows-netfx3-ondemand-package.cab file and drop it on the Update page.  It will now get installed with the other updates you have selected into your updated install.wim.
