Surface pro 4 - clock speed of CPU keeps the same

Anonymous

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?

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.

    After the update my SP4 is very very very slow!

    in idle it runs @ 0,49 mhz while connected to power adapter! 

    while typing this post, is 0,6mhz and there is a 0,5 seconds lag between characters!

    ****?

    After adding to the registry this:

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\8baa4a8a-14c6-4451-8e8b-14bdbd197537]

    "Attributes"=dword:00000002

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\36687f9e-e3a5-4dbf-b1dc-15eb381c6863]

    "Attributes"=dword:00000002

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\cfeda3d0-7697-4566-a922-a9086cd49dfa]

    "Attributes"=dword:00000002

    now the system become reactive, even if these should only enable advanced options to the power management panel...

    is my sp4 sensitive?

    Hi, Kent

    I tried to re-install the update and found that the CPU speed is normal at first. Then I restart the SP4, the speed increased again. It might be related to some bugs of the system. Everything is fine with the previous version of windows 10.
