Windows 7 Upgrade Chart
 

I’ve explained some of the challenges and limitations that will be involved in upgrading an existing Windows XP or Windows Vista PC to the forthcoming Windows 7 operating system, due out October 22. Several readers asked me to publish a chart showing which current versions of Windows could be easily upgraded to which planned versions of Windows 7, and which couldn’t. So I asked Microsoft to supply such a chart we could publish, and the company graciously did so. It is reproduced below, unaltered.


Common consumer versions of XP and Vista are listed down the side, and the three (out of a total of six) planned versions of Windows 7 likeliest to be used by average consumers on existing PCs are listed across the top.

Note that ONLY those combinations which intersect in a green box saying “In-Place Upgrade” can be upgraded in a simple way that, in Microsoft’s words, “Keeps your files, settings, and programs intact from your current version of Windows.”
