Unlike desktop CPUs, the Z3735F is a System-on-a-Chip (SoC). This means the "processor driver" is actually a collection of drivers that manage everything from power consumption to integrated graphics.
The post mentioned a specific driver version, 1.2.15.0, which seemed to be the magic solution. John downloaded the driver and installed it, holding his breath as the device restarted. To his delight, the Windows 10 installation recognized the CPU, and the device began to hum along smoothly. intel-r- atom-tm- cpu z3735f - 1.33ghz driver download
