Many people do not realize why their computer screens tend to accumulate a layer of dust. (It is due to the generation of static electricity.)
Most people clean their computer screen, from time to time, by wiping the
dust off with a rag when the accumulation of dust gets to the point that it is annoying.
What many people do not realize is that static electricity also
causes a thin layer of film to build up on the inside of your screen, as well. (This is why old computer screens aren't as "sharp" as new ones.)
Fortunately, a newly released, but unpublicized, utility included in your
operating system's latest automatic update solves this problem.
You will be delighted with the new clarity of your screen!
