There are new hidden processor power settings in Windows10: 8baa4a8a-14c6-4451-8e8b-14bdbd197537 - Processor performance autonomous mode (Enable/Disable) Specify whether processors should autonomously determine their target performance state. 36687f9e-e3a5-4dbf-b1dc-15eb381c6863 - Processor energy performance preference policy (Percent) Specify how much processors should favor energy savings over performance when operating in autonomous mode. cfeda3d0-7697-4566-a922-a9086cd49dfa - Processor autonomous activity window (Microseconds) Specify the time period over which to observe processor utilization when operating in autonomous mode. 4e4450b3-6179-4e91-b8f1-5bb9938f81a1 - Processor duty cycling Specify whether the processor may use duty cycling.

You can get and set them through powercfg.exe. But I prefer to unhide them - change their REG_DWORD value Attributes from 1 to 0 - and they will be shown in advanced power settings dialog under the "Processor power management" root node. After the update to 1607 I noticed that Processor performance autonomous mode was enabled both in Perfomance and Balanced power plan. Article above says about Skylake CPUs and I have IvyBridge-E one. So I disabled this autonomous mode just in case. Guys with Skylake+ CPUs can check these settings on their rigs.
