GCFLearnfree is a site on youtube which has video tutorials to help you learn the basics of many things without (they say) your being bored to tears. Included in their huge range of videos are a number relating to the basics of information technology e.g: Windows explorer, Microsoft programmes such as Excel and Word and some Apple Mac programmes too. Just look around for what you need.
Thanks to Cheryl Twomey for suggesting this.
