+## Preface
+
+The changelog for Windows updates KB4012218 and KB4012219 included the following:
+
+> Enabled detection of processor generation and hardware support when PC tries to scan or download updates through Windows Update.
+
+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.
+
+It is 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.
+
+This has even affected people with older Intel and AMD processors! I've received user reports of the [Intel Atom Z530](../../issues/7), [Intel Core i5-M 560](../../issues/23), [Intel Core i5-4300M](../../issues/24), [Intel Atom D525](../../issues/34), [Intel Pentium B940](../../issues/63), [AMD FX-8350](../../issues/32), and [AMD Turion 64 Mobile Technology ML-34](../../issues/80) all being blocked from receiving updates.
+
+## Bad Microsoft!
+
+If you are interested, you can read my original write up on discovering the CPU check [here](../../tree/old-kb4012218-19).
+
+## How it works
+
+Basically, inside a file called `wuaueng.dll` there are two functions: [`IsDeviceServiceable(void)`](https://gist.github.com/zeffy/e5ec266952932bc905eb0cbc6ed72185) and [`IsCPUSupported(void)`](https://gist.github.com/zeffy/1a8f8984d2bec97ae24af63a76278694). `IsDeviceServiceable(void)` is essentially a wrapper around `IsCPUSupported(void)` that caches the result it receives and recycles it on subsequent calls.
+
+My patch takes advantage of this result caching behavior by setting the "first run" value to `FALSE` and the cached result to `TRUE`.
+
+- At system boot the wufuc scheduled task runs as the `NT AUTHORITY\SYSTEM` user.
+- `wufuc` determines what service host group process the Windows Update service runs in (typically `netsvcs`), and injects itself into it.
+- Once injected, it applies a hook to `LoadLibraryEx` that automatically patches `wuaueng.dll` when it is loaded.
+- Any previously loaded `wuaueng.dll` is also patched.
+
+### Several improvements over my batchfile method:
+
+- **No system files are modified!**
+- Heuristic-based patching, which means it will usually keep working even after new updates come out.
+- C is best language!
+- No external dependencies.
