Forces the specified window to close.

WinKill [, WinTitle, WinText, SecondsToWait, ExcludeTitle, ExcludeText]



WinTitle The title or partial title of the target window (the matching behavior is determined by SetTitleMatchMode). If this and the other 3 window parameters are blank or omitted, the Last Found Window will be used. If this is the letter A and the other 3 window parameters are blank or omitted, the active window will be used. To use a window class, specify ahk_class ExactClassName (shown by Window Spy). To use a process identifier (PID), specify ahk_pid %VarContainingPID%. To kill a group of windows, specify ahk_group GroupName (WinText, ExcludeTitle, and ExcludeText must be blank in this case). To use a window's unique ID number, specify ahk_id %VarContainingID%. The search can be narrowed by specifying multiple criteria. For example: My File.txt ahk_class Notepad
WinText If present, this parameter must be a substring from a single text element of the target window (as revealed by the included Window Spy utility). Hidden text elements are detected if DetectHiddenText is ON.
SecondsToWait If omitted or blank, the command will not wait at all. If 0, it will wait 500ms. Otherwise, it will wait the indicated number of seconds (can contain a decimal point or be an expression) for the window to close. If the window does not close within that period, the script will continue. ErrorLevel is not set by this command, so use IfWinExist or WinWaitClose if you need to determine for certain that a window is closed.
ExcludeTitle Windows whose titles include this value will not be considered.
ExcludeText Windows whose text include this value will not be considered.



This command first makes a brief attempt to close the window normally. If that fails, it will attempt to force the window closed by terminating its process.

If a matching window is active, that window will be closed in preference to any other matching window beneath it. In general, if more than one window matches, the topmost (most recently used) will be closed.

This command operates only upon the topmost matching window except when WinTitle is ahk_group GroupName, in which case all windows in the group are affected.

Window titles and text are always case sensitive. Hidden windows are not detected unless DetectHiddenWindows has been turned on.
