Aside from the core aspects of Windows 7 and Windows 8, I don’t regularly use any Microsoft products (almost all of what I do is in the cloud). But if I was going to dive into the world of Microsoft, I would start by looking through this collection of more than 100 ebooks about Microsoft products. In the collection you can find ebooks on everything from Windows 7 & 8 keyboard shortcuts to programming Windows Store apps.

Applications for Education
A few of the ebooks in this collection that might be of interest to educators are BYOD Devices – A Deployment Guide for Education, Getting to Know Office 365, and Windows To Go – A Deployment Guide for Education (all links open PDFs).
