There is one explanation for that (Aug 09). At that time, prior to the release of Windows 7, computer sales were down bad. There was the offer for a free Windows 7 disc, once it was released, not many bit at the offer. You don't really think those computers were thrown in the dumpster, do you? In my recovery partition, there are some similar dates for installation (July 09). In fact, when I had Linux on this computer, on the startup screen with the option of what partition to boot, the recovery partition shows as Vista, the other Windows 7. The OEM's took those computers, modified the recovery partition a little, loaded Windows 7 on them, and put many of them on sale. In fact, mine was discounted $100. I know, because I had been eyeballing this one, one from Dell and one from Toshiba. All three were available during the mid summer of last year. Instead of buying as soon as 7 was released, I laid back and waited to see who would blink first. HP did, reducing prices on a lot of computers. It was in a PC World article that I discovered the three of them. They were all budget models, but ranked high in quality for the money. I just went out to where the box the computer was in (the OEM box), there's a date tag, 2009/08/30. That's almost two months before 7 was released. But that recovery partition shown as Vista (by Linux) tells a lot. No corporation is going to trash that many computers over an OS change.
