[Elecraft] Best Reference Book for Win 7 and Win 8.1?

[Jim Brown]

I've recently replaced one of my computers with a Win7-64 Pro machine, 
and my XYL's with a Win 8.1 box. There are certain "wierdnesses" with 
both of these OSs that I'm finding baffling, so I've decided that I must 
RTFM.

I used to do this by grabbing a bunch of such books from the rack at 
Borders or Barnes and Noble, and a cup of coffee, and buy the one (or 
two) whose writing style communicated well with me. Here in Santa Cruz, 
that option is no longer available. Suggestions?
