Have you got loads of windows open at once and find your screen too
cluttered?
In Windows 7 and up, click and hold on the title bar of the
window you’re
interested in and give it a shake back and forth with your
mouse. All other
windows will shrink to the taskbar, leaving the window
you’ve made dizzy
remaining open.
This feature is known as Aero Shake. You can get Aero features in Windows
Vista or XP using third party applications.
