Fixing "SecurityHealthSystray.exe - Bad Image" (0xc000012f) When Nothing Normal Works

sfc, DISM, and a full in-place repair install all failed to fix a corrupted SecurityHealthSSO.dll. Here is what actually worked: pulling the real DLL from the standalone SecurityHealthSetup.exe installer and writing it into System32 from a Linux live USB, since Windows Resource Protection blocks every other path, even Microsoft’s own signed repair tool.
