How is it underhanded?
Those updates are not tested against your newer CPU, because that product is not supported on your CPU. Why would any company ship a release that they knew with 100% certainty had never been formally tested on a configuration. (Usual suspects, please resist the urge to look like a fucking idiot...)
Most likely the updates will work, but maybe they'll screw your system performance too. Remember, most of the fancy low-power and clock-speed regulation features in the latest CPUs are completely invisible to Windows 7's kernel: you're basically running with whatever Intel/AMD sets those registers to at reset time.
I understand why someone would prefer Linux to Windows 10, but then Linux is a modern, supported OS. Windows 7 isn't anymore. It's time to move on.
