I have not edited the registry at all. Jars work fine.
If I edit the registry to alter javaw to java then the jar also runs, but in a command shell with the standard 
output/error going to the command shell.
After changing it back to javaw it continues to work as expected.

Is your system a fresh install of W10, or an upgrade?
If it's an upgrade, maybe there is something you have done in the history of the original Windows that has adversely 
affected the operation of javaw.exe/java.exe after upgrading to W10.

The machine I tested it on is a Surface 3 Pro, which was originally supplied with W8, later upgraded to W8.1 and then to 
W10. If your upgrade path is different that may explain the different end results.
