Consumers reports has implored Microsoft to extend support for Windows 10: 

"Is Microsoft hypocritical? Consumer Reports asks CEO Satya Nadella to make Windows 10 support extension free for 400 million PCs".

Perhaps this additional pressure will impact Microsoft's decision and as a by product, Intuit's ill-advised decision to do away with the desktop version of TT for Win 10 as well. The proclaimed security justification is specious. The profit motive, on the other hand, is not.
