Many of you have already come across the Official Windows Vista Product Guide, which was available since some time. Its a comprehensive feature-by-feature guide to Windows Vista. With contributions from people who actually worked on the product, this is the definitive resource to learn about Windows Vista. The Windows Vista Product Guide is available in the new Microsoft Word 2007 or the new XPS format.
Its a must read for those interested in learning about Vista.
The product guide is available a s a Microsoft Office Word 2007 document (65MB) or XPS (25MB). In order to view the XPS doument, you will need to install the reader (included in Windows Vista).
If you want to view the product guide in XPS format in Windows XP or Windows Server 2003, you can download the viewer here.
Talking of Vista Guides, I found another Vista guide from the Windows Vista Magazine , its written by Mike Halsey.
The magazine says about the guide :
"Mike Halsey has created a really in depth look at Windows Vista that everyone should at least have a look at. It includes an appendix on how to get started with Microsoft Office 2007"
Indeed its a nice guide which takes you through the some advanced options, utilities and tweaks in Vista.
You can download it from here .
It has been nicely presented with lots of screenshots.
