Earlier this year I made a series of DVD video versions of a few of Microsoft Press’ Step by Step books. These were never released commercially but have now been released instead completely free online.
Here is 5½ hours of video I made from the Windows 7 Step by Step book.
There are 12 video lessons in total that do on occasion refer to the practice files that come with the book. These are not necessary to follow the exercises however.
All videos are available in HD.
