Interested in Windows 7? (I suggest you should, it really rocks) Anyway, if you want to do a little more reading before jumping in, or you’re one of the early adopters to the OS, you may want to download Microsoft’s 140-page user guide from their site. At 140 pages, it’s definitely comprehensive and contains lots of information for both new and experienced users. You can download the document either in PDF or XPS form from this link. Otherwise, you may also read my Windows 7 blog post.
