There are screen-recording programs, such as Hypercam, that allow the user to record what's happening. Be sure to get whatever you end up getting from a trusted download site, such as Download.com or CNET.
I make videos for youtube, so I think i can help you,
1. People have screen recorders (for example hypercam, camstudio etc.) (be careful what you download so you dont end up with a virus). 2. you gotta get used to your screen recorder. 3. You need an editing program, for example, window movie maker usually comes with some computers. But you can download some editing programs, but they might cost money(so be careful what you download) 4. Once your done editing, go to youtube and upload video, but you need an account to upload. 5. Happy video making
