Windows only: When you need to access your desktop, it's just a quick WIN+D away, right? Sure, if you don't mind stuffing everything back into the taskbar. Desk Topmost pulls up your desktop for quick file access.
Desk Topmost, when activated via hotkey, floats your desktop over your existing windows so you can access any folders or shortcuts you have there. If your desktop is spartan, the tool won't be of much use, but for people who use their desktops for collection, Desk Topmost is a handy tool. By floating your desktop to the top of the pile, you spare yourself the lag that occurs when you minimise numerous open windows. Desk Topmost is available for Windows 2000 through Windows 7, but be forewarned that the transparency only works on Windows Vista and forward. Desk Topmost is freeware, Windows only.
