Default windows layout settings?

[JulyJim]

In an  obvious case this has been asked before I apology for wasting your precious time.
In C:B search or Google did not help.

After trying C:B for abut a week I managed to display the main  cpp file window only and couldn't  get back to starting, as in initial load , with multiple windows display.
Than to make things worse - somehow I got to "full screen" ( main.cpp) and there I am stuck.
Reloading C:B and using  "last project": does not help.

Is there a "reset to default  / original layout " way ?
Thanks

I may have stumbled on partial  answer - double click gets me back to  original; layout, but still in "full screen"

Look into the "View" menu.
