Aero Peak lets you ‘peak’ behind all the windows so that you can have a look at your desktop, should you wish to access any gadgets or shortcuts. Peek Through is a freeware application for Windows 7, Vista & XP which makes the foreground window transparent with the press of Hot Keys.
Peek Through lets you adjust the amount of transparency and choose the Hot Keys. You also have the ability to “click through” the transparent window onto the window beneath it.
After selecting your settings, click the Activate button, the application will then be minimized to the system tray. You may minimize the program window to send it to the system tray, or close it to exit the program.
Clicking the icon in the system tray will bring the window back up. Simply pressing the Hot Keys will enable the transparency and pressing them again will remove the transparency.
To see what it’s all about, give Peek Through a try!
