When working with multiple windows minimized on the taskbar, it can be troublesome to switch between windows one after the other, especially when they are grouped and hidden one behind the other. Windows 7 groups several folders together, but you have the option to disable this feature. Right-click on the taskbar and select properties. You’ll see a window that says ‘Taskbar and Start Menu Properties’. Here, under the Taskbar tab, look for ‘Taskbar buttons’. From the drop down menu, you can opt to ‘Never Combine’.
But here’s an effective way to toggle between windows while they are combined. When multiple folders are open, push [Ctrl] on the keyboard and click on the group icon. With each click of the mouse, the folders pop up consecutively.
Note: The beta version of Windows 7 RC, which might still be in use, groups the buttons only once the taskbar is full. You can choose to group the windows by selecting the option ‘Always group, hide captions’ from Taskbar and Start Menu Properties.
