A screen saver is a moving picture or pattern that appears on your computer screen when you haven’t used the mouse or keyboard for a specified period of time. Screen savers were originally used to save older, monochromatic monitors from damage, but now they’re mainly a way to personalize your computer or enhance its security by offering password protection. There are many nice screen savers which can be downloaded from the Internet such as the popular matrix or simply a fake blue screen of death.
Screen saver can be annoying as well if you want your screen to stay on for a little longer such as playing a video demonstration. It can be disabled either from Control Panel or simply right click on desktop and select Personalize. Then click on Screen Saver and select (None) from the drop down menu. You would have to do the same thing to re-enable screen saver again.

To save the trouble, you can just run a portable application called Keep Display On. It does not have any configuration, except a text showing “As long as this program is running, the screensaver will not start.” It does exactly what it says by hooking the Windows API and temporarily deactivates the screen saver. Keep Display On takes up merely 1MB from memory when it is running. We have tested it on Windows 7 and it worked perfectly.

Good painters are able to use a pencil to sketch a person’s face or even a scenery to a drawing pad but even a person who can’t paint or draw can now provide a sketch based on a digital photo. This can be done instantly and automatically using a free software called Instant Photo Sketch.
Instant Photo Sketch can support many major image formats such as PNG, JPG, BMP, JPEG, TIFF, TIF and GIF. All you need to do is load the image to the program and drag the slider to adjust the level of detail. Moving the slider to the left for more detail and darker sketch and to the right for less detail and brighter sketch. The result looks exactly the same as the original photo except it is in pencil sketch. Clicking the Save button allows you to save the converted photo into either JPG or PNG format. It also has a zoom button for you to zoom the sketch

Everything works as expected but the Edit menu seems to be incomplete as it doesn’t contain any function. Instant Photo Sketch is free to use and is able to run on Windows.
