These updates marked the implementation of a [policy change](https://blogs.windows.com/windowsexperience/2016/01/15/windows-10-embracing-silicon-innovation/) they announced some time ago, where Microsoft stated that they would not be supporting Windows 7 or 8.1 on next-gen Intel, AMD and Qualcomm processors.
This was essentially a big middle finger to anyone who decides to not "upgrade" to the steaming pile of :shit: known as Windows 10, especially considering the extended support periods for Windows 7 and 8.1 won't be ending until January 4, 2020 and January 10, 2023 respectively.

`IsDeviceServiceable` simply calls `IsCPUSupported` once, and then re-uses the result that it receives on subsequent calls.
