To answer the questions I have made a couple of videos that give users a Windows 10 First Looks & Impressions and Windows 10 Tutorial.
The videos go through the new features, show you some tips and tricks and also explain more fully new features such as Cortana, Edge, the Microsoft Store and Groove Music.
If you have any questions please leave them below or in the comments section of Youtube and I will try my best to answer them for you.
