I figure, if done and presented correctly, it will take about 5 tutorials to answer 98% of any questions about Windows 10. Such things as how to make a Public Network a Private Network should be very popular. And it should not be much of a stretch to find other common questions. The ones concerning licensing and upgrades might be one in which an explanation of "we don't know" might be the best approach. There will probably be a flurry of questions the first day or so after the Windows 10 public release starting on July 31st. It would be nice to have clear and concise tutorials to point to for explanations.
