here's how I checked and found Microsoft don't sell Win 7 any more - despite some old pages that aren't part of their shop now.

www.microsoft. com - - click on the hot link 'Store' -- click on the hot link 'Windows'

and you get a full page ad about Win 8 with a line 'Like Windows 7 only better' with all the prices.

Hover over the hot link on the left that says 'Windows' and you get the choice of two links "Windows 8' or 'Windows 8 Pro' - nowhere in the store is there Windows 7 available for sale or download.
