OK, you might not be in the OneNote 2007 beta program, but this is a one of those "save for later" tidbits that can come in handy. OneNote 2007 has a fairly extensive guide to get you started once you install and open the product. While you might zip through the guide and decide you’ll never need it again, what happens if you close it or worse…you *gulp* delete it?
Have no fear because the OneNote Extensibility blog is here! Solutions to restore or reload the OneNote Guide are available here. If you’re interested in the new features or want view a OneNote 2007 demo, Microsoft offers plenty of info on the OneNote page.
