The chart above is NOT from Microsoft. 

Ed Bott, over at ZDNet, was able to quickly redesign the Windows 7 Upgrade Chart from Microsoft in about an hour.  And Ed's a journalist.

The original chart (below) is unnecessarily complicated and hard to comprehend.  I generally don't post about bad infographics, but in this case Ed was able to re-do Microsoft's chart into the improved, simpler version you see above. 

Honestly, the upgrade process is still too complicated and Microsoft should be ashamed of themselves.  This deserves a new Mac vs. PC ad just by itself.

Found on Engadget and All Things D.

Here's the official "horrendous" (I don't get to use that word often) chart from Microsoft.
