>How would I close specific windows using WSH? The window title is a given.

AFAIK, the WSH doesn't provide a COM wrapper for this functionality. You have to use the WinAPI directly. Erik Moore has a write up on how to do this in the API section. Here is an example (paraphrased):

#DEFINE WM_CLOSE 0x10
declare integer FindWindow in "user32" string lpclass, string lptitle
declare integer SendMessageA in "user32" as "SendMessage" integer hwnd, integer wMsg, integer wParam, integer lParam

lnwnd = FindWindow(.NULL.,MyWindowTitleHere)

if lnwnd > 0 then
	=SendMessage(lnwnd,WM_CLOSE, 0, 0)
else
	wait 'Unable to find window' window
endif

HTH.
