We've got multiple bugs being talked about here.
This thread is about multiple exes not shutting down on close.
I think the other is about Nwjs not running on Windows 10.
Trying one bugs solution might work for the other, but logic would indicate otherwise.
Agreed. Though I'm on Win 10 and everything else is working (minus the left over nw.exe)
What baffles me is... ( correct me if I'm wrong here ) Multiple instances when running/previewing a project seems to be normal. Not seeing the issue there considering the fact that NW is based on chromium and when you open a single chrome window you get multiple chrome.exe instances in your task manager.
Example
as you can see multiple tasks for single chrome window... And a left over nw.exe
I think the main issue is once a project/preview is closed a remaining instance of NW.exe is still active.
