In my humble opinion, Mark Minasi authors the best manuals for Microsoft Windows anywhere. Starting with a book on OS-2, Mark has been providing professionally written documentation since 1988. I can’t say that these books are appropriate for absolute beginners, but they’re just the thing for intermediate and advanced users who wish to master a new version of Windows.
You can find his books at http://www.minasi.com/books , Amazon. Com, or your local bookseller.
