DesktopZoom

DesktopZoom is a complete zoom tool that enables you to see even the smallest pixels of any window, application, document or picture opened in your computer, thanks to an incredible zooming capacity.

The program doesn't require installation. It features a wide range of options, with which to zoom in the entire desktop, an active window or just the area below the cursor.

The downside to it is that there are so many possibilities that the interface seems a bit confusing. Also, I find that sometimes the zoom effect is difficult to control, especially when zooming the whole desktop.

DesktopZoom magnifies your screen and lets you see things in detail.
