Windows 8.1 Installed by an Expert

My long time colleague Walter Riker waxes technical about his installation of Windows 8.1  He is also an expert on Office 365 (He teaches it for companies).  and describes how the two coexist.  I installed 8.1 only a week ago, and have found it quite behaved and incremental.   Now there are others I have to convince that it is not evil.
