Of course habrás noticed that MS Paint only has the option of Zoom of 1x, 2x, 6x and 8x, but in fact there is a fifth increase (10x) that for some reason was removed (by half) of the final version. The programmers removed the icon of the bar of hardware, but they left a small space without icon but that activates the Zoom function 10x.

To have access to this "secret" tool:

1. It sees to MS Paint and opens or creates an any image.
2. In the bar of hardware of the left, it gives clic in the Zoom tool and selects the increase 8x so that you see the difference.
3. Now if you look carefully, under the Zoom icon 8x there is a small empty area, which rather looks like a line.
4. It gives clic in this area and you will see how there is an increase more than the original of 8x in your image.

Here an explanatory video is of how obtaining this.
