CloseWin is a portable application which can immediately close multiple windows in the taskbar at one time.
If you like to open a lot of windows at the same time. You probably need to spend some time to close them after use, so that you won’t accidentally close the wrong window. So, why not use CloseWin to help you close the unused windows?

You will need to add some text to the list, so that CloseWin can close all windows that contain the text in the title. For example, i had added “Skype” to the list. When i click “Close selected windows“, CloseWin will close all opened windows which contains “Skype” in the title. Remember, the text is case-sensitive!
You can add different text to the list, and then click “Close all windows in list” so that you can close multiple selected windows simultaneously.The last options – “Close All Windows”, will close all windows in taskbar.
Note: There are some applications which can’t be closed by CloseWin, but most of the applications work fine.
