How can I close all opened New Windows that are currently open?

[#1]

I am looking to close all of the opened New Windows open, how can this be achieved?

[#2 · Accepted solution]

Use Get Window List() in combination with << Close Window (and looping)

[#3]

For scripting @jthi s answer applies, and interactively you can go to the home window, select all windows in the window list (Crtl-A), and in context menu (right mouse click) you can close them all.

another way is window/Close All 

also nice:
If you open the window menu from a data table, you have the option to Close All Data Tables,

from a report you can Close all Reports,

and so forth.

very convenient
