Windows 7 Aero brings two new ways to view your open windows. These are: Peek, also known as Aero Peek. You can peek behind all your open windows to see the desktop. This will allow you to see objects on the desktop such as shortcuts and whatever gadgets that you have installed and running. Computers that are purchased with Windows 7 preinstalled will not have a problem with Windows 7 Aero but if you upgraded your computer to Windows 7 you have to make sure that your system meets the minimum requirement. Minimum 1 GHz CPU for Windows 7 32-bit /64-bit, 1 GB of RAM  128 MB of Video RAM with support for DirectX 9. If your computer does not meet these specifications then Windows 7 Aero will not be enabled by default. You can view a specific window that was covered by others before. I know that there are other ways to do this in previous iterations of Windows (show desktop button) but Windows 7 Aero makes it an easier and smoother transition. Now you can see the desktop by moving your mouse cursor over a rectangular button located in the very lower rightmost of the screen, just to the right of the date/time in the taskbar. When you move your mouse cursor over the block in the lower right corner open windows become transparent except for their outlines. As shown here. Moving your cursor away from the rectangular button will make your open windows reappear in their present positions. To minimize all open windows to show only the desktop all you have to do is click your mouse button on the rectangular button. Note: You can turn off the Windows 7 Aero function if you want to, returning the function back to the previous Windows version of show desktop. It can be turned off in the Taskbar pane of the Taskbar and the Start Menu Properties window. Full-Screen Window Preview You can preview any of the open windows on your desktop while hiding other open windows. Move your cursor over the taskbar button for an open application or other window. A new thumbnail appears, previewing the window in a small thumbnail frame. Move your mouse cursor over one of the thumbnails. Other open windows on the screen become hidden and show only the outlines of the windows. Now the only window visible is the selected window. You can select a previewed window by clicking on its thumbnail. You can also close a window by clicking on the red "X" in the thumbnail. Windows 7 Aero is available in Windows 7 versions - Home Premium, Professional and Ultimate.
