Hide Windows solves the problem of your cluttering taskbar. If you have a window open which you don't need to access frequently then simply go to that window [make that windows the active window] and while it is focus, click the icon of Hide Windows in the System Tray with the left mouse button. This will hide the window from the desktop and taskbar. This makes your taskbar clutter-free. 'Hide Windows' is also built to run without any installation. The only system needed to run this software is the Visual Basic Virtual Machine 6.0 [msvbvm60.dll]. Most of you people must already be having this file in your computer because this file is needed by many softwares which you might have installed earlier.
