See how to do it
A lot of the content on the Web is now in the form of videos. You can find all sorts of things at You Tube, of course, but there are other interesting sites as well. You want to know how to do something? A site called WonderHowTo may very well have a video illustrating what you want. It has videos on all sorts of subjects and I looked at a few on computer subjects. They were not made by professionals and varied in quality but still might be helpful.
The videos are not on one site but come from a variety of sources, including You Tube. As always on the Web, be wary about what you download.
