1. Patch `wuaueng.dll` and change `dword_600002EE948` (see [this line](https://gist.github.com/zeffy/e5ec266952932bc905eb0cbc6ed72185#file-isdeviceserviceable-c-L7)) which is at file offset `0x26C948`, from `0x01` to `0x00`, which makes `IsDeviceServiceable(void)` jump over its entire body and return 1 (supported CPU) immediately. This is my preferred method. **These offsets are only for the Windows 7 x64 version, I will upload `.xdelta` files for all of the other versions eventually. I haven't tested this yet, because I don't want to install this garbage update onto my PC, so it'll take me a while to test everything in a VM.**
2. Patch `wuaueng.dll` and `nop` out all the instructions highlighted [here](https://gist.github.com/zeffy/e5ec266952932bc905eb0cbc6ed72185#file-isdeviceserviceable-asm-L24-L26) in `IsDeviceServiceable(void)`, this will enable the usage of the `ForceUnsupportedCPU` of type `REG_DWORD` under the registry key `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Test\Scan` (you will need most likely have to create this registry key). Set this value to `0x00000001` to force unsupported CPUs, and back to `0x00000000` to change the behaviour back to default. You will probably need to restart your PC or restart the `wuauserv` service in order for changes to apply. **This behaviour is undocumented and could be removed in future updates.**
