Fixed with today's update. Thanks, MS!
NOTE: I had to reboot twice after updating. So if anyone is not seeing the fix try a restart.
Surface pro 4 - clock speed of CPU keeps the same

After updating to windows 10 (1607), I find that the clock speed of the CPU keeps to be 2.92GHz when plugged, and to be 2.47GHz when using battery. My surface pro 4 has a core i5 CPU. It seems strange because the clock speed of CPU should change with the workload in the Task Manager. Does anyone have the same problem?

2016-08-03T21:14:13+00:00 I completely agree. They told me that I needed to get a new SP4, but I declined to get a refurb when I have been taking very good care of my device from day 1. Hopefully they will be able to update their drivers or issues ASAP. Until then, I created a new power plan that stays at 50%. Now, I only have my CPU at 1.17ghz rather than 2.90+.
Much slower, but I guess I can handle it. What really drove me crazy was the constant fan turning on when doing NOTHING!

2016-08-03T21:11:49+00:00 A friend of mine found a solution to the problem. Add the following to an empty text file and rename it as a .reg file:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7] "Attributes"=dword:00000002
Run the file, and reboot. Once your computer has restarted, go to settings>system>power&sleep>Additional power settings>Change plan settings>Change advanced power settings. You'll notice that there's an option to set boost mode for battery mode and plugged in mode, that turbo boost is disabled for battery mode by default, and plugged in mode is set to aggressive by default. You can change these settings to whatever you want.
