You may recall that Microsoft offered and then withdrew a Vista product guide in early April, but Greg Keizer now reports at TechWeb that it is back in all its massive glory:
“Windows Vista Product Guide” can be downloaded from here in either Word format or the original XPS (XML Paper Specification) format, which Microsoft touts as a replacement for Adobe’s popular PDF. The latter requires an XPS viewer application to read the guide in Windows XP. (Caveat: The Word document is approximately 60MB in size.)
I opted for the Word version and would say that it’s a credible high level catalog and explanation of Vista features and versions,.
