WinMinimize WinTitle, WinText, ExcludeTitle, ExcludeText



Type: String, Integer or Object

A window title or other criteria identifying the target window. See WinTitle.


Type: String

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.


Type: String

Windows whose titles include this value will not be considered.


Type: String

Windows whose text include this value will not be considered.

Error Handling

An exception is thrown if the window could not be found, except if the group mode is used.


Use WinRestore or WinMaximize to unminimize a window.

If a particular type of window does not respond correctly to WinMinimize, try using the following instead:

PostMessage 0x112, 0xF020,,, WinTitle, WinText ; 0x112 = WM_SYSCOMMAND, 0xF020 = SC_MINIMIZE

This function 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 case sensitive. Hidden windows are not detected unless DetectHiddenWindows has been turned on.
