Now that the new "Edge" browser is out in the world, users are learning that it does not support NPAPI plugins, including Java in a manner similar to that change in the Chrome browser several months ago. This can also be an issue with ActiveX and Silverlight
It appears that the MS workaround for that is a way to activate IE 11under Windows 10. You can run that by creating a shortcut to: c:\program files\internet explorer\iexplore.exe
But...many of us have already gotten used to having more than one browser installed and "ready" for those websites that just seem to be optimized for a certain browser, or where a desired applet does not have an alternative.
Firefox continues to be a viable second choice for Win 10 bowsing
