At the end of this month, Microsoft will pull the plug on the sales of Windows 7 licenses to OEMs for most versions of the OS. What this means is that vendors, such as HP and Dell, can no longer buy the licence keys from Microsoft for the OS, but they will still be able to sell through their existing stock. So, on November 1st, Windows 7 machines wont disappear completely but they will quickly become much harder to find. For Dell and HP, this is not good news as both companies are still pushing the five-year-old OS with promotions and prominent placing on their websites. As you can see in the images in this post, HP and Dell are still attracting enough customers who want Windows 7 to warrant placing links that are highly visible on their websites.
