This doesn't work:
Is there a keyboard shortcut to close a window in Windows?
I have Windows 3.1 on old pc, few windows open. I cannot close using Alt+F4 as suggested here, because the whole windows session wants to close. Having no muse, how can I close active window without exiting windows?
Alt + Tabs flicks through open windows, but regardless which one is active Alt+F4 always wants to close windows.

In Windows 3.1, to close a sub-Window without exiting Windows itself, be in the sub-Window (that window active), and use Ctrl-F4 to close the window. This works without exiting Windows.
