The appearance for looking at PATH variable in Windows 10 now looks different than either it did before some previous update or than from Windows Vista.
Going to system information from Control Panel (and Control Panel no longer shown when right-click on the Start Menu button), and Advanced link, and then the Environment Variables button, clicking on PATH in the lower listbox, and click the EDIT... button, now I see a LISTING of items as like in a listbox - no trail of items separated by semicolons. I am not sure what to do with this if I wanted to change something.
How do I understand this? What would I do if I were to install Java SDK and want to set a new addition to the PATH variable?
