WinKill

Forces the specified window to close.

WinKill , WinTitle, WinText, SecondsToWait, ExcludeTitle, ExcludeText

Parameters

WinTitle, WinText, ExcludeTitle, ExcludeText

If each of these is blank or omitted, the Last Found Window will be used. Otherwise, specify for WinTitle a window title or other criteria to identify the target window and/or for WinText a substring from a single text element of the target window (as revealed by the included Window Spy utility).

ExcludeTitle and ExcludeText can be used to exclude one or more windows by their title or text. Their specification is similar to WinTitle and WinText, except that ExcludeTitle does not recognize any criteria other than the window title.

Window titles and text are case-sensitive. By default, hidden windows are not detected and hidden text elements are detected, unless changed with DetectHiddenWindows and DetectHiddenText. By default, a window title must start with the specified WinTitle or ExcludeTitle to be a match, unless changed with SetTitleMatchMode.

SecondsToWait

If blank or omitted, the command will not wait at all. If 0, it will wait 500 ms. Otherwise, specify the number of seconds (can contain a decimal point or be an expression) to wait for the window to close. If the window does not close within that period, the script will continue.

Remarks

This command first makes a brief attempt to close the window normally. If that fails, the command 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. In general, if more than one window matches, the topmost (most recently used) will be closed.

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

ErrorLevel is not set by this command, so use WinExist(), IfWinExist or WinWaitClose if you need to determine for certain that a window is closed.

While the command is in a waiting state, new threads can be launched via hotkey, custom menu item, or timer.
