No I mean Win7 could last so much longer. XP lasted like a really long time compared to 7.
Windows XP had been adapted to many, many commercial machines including ATMs and security terminals. Support was expanded because the companies that operated the machines couldn't afford to upgrade them at the time, and they petitioned Microsoft. If security, banking and other large commercial sectors had actually bothered to keep their equipment up to date (unsurprising given cost and time), then Windows XP would have been cut loose a long time ago.
Windows 7 is not in the same category, and is not used in anywhere near as many important commercial devices. Microsoft doesn't really care about its consumer clientele since they're not paying them to keep the system secure past its expiration date.
Microsoft doesn't have enough resources to manage 3+ OSs at once. It's time Windows 7 was archived.
