1. Create a "C/C++ Application" project
2. In the project options change "Console Type" to "External Terminal"
3. Run the project
4. Note 3 processes has been created: conhost.exe (twice) and cmd.exe
5. In the terminal window you have the prompt "Press [Enter] to close the terminal ..." - do it
6. Note that one of conhost.exe disappeared, but the others are still there
7. Do it several times - you will have a lot of conhost.exe and cmd.exe processes hanging.
8. Close NetBeans and the processes will disappear.

Can confirm this behaviour on Windows 10
Fixed in the internal repo (ba575e43c807).
The fixed version will be available in Dev build in a couple of days.
Thanks for the detailed bug report, it helped me a lot.
Integrated into 'main-silver', will be available in build *201612080001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
