Note: Windows 10 Build 14393.3 is (reportedly) the final RTM build, scheduled for release on Aug.2.
First noticed Reparse Point errors on Win 10 several builds previous.
Was hoping that updating to a newer Win 10 build number would have repaired the Reparse Points error, but unfortunately did not.
What prompted the diagnosis attempt, was that a certain older program needed Dot NET 3.5, which was balking when using the normal installation procedure.
Dot NET 3.5 is an optional feature that can be installed on an as-needed basis from the Win10 installation media.
