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.

    No wipe needed, I kept everything and re-installed the updated on top of the existing system.

    I updated to 1607 and reset my SP4. Then I use the Media Creation Tool to re-install the update. Luckily, the clock speed of CPU steps down.

    I just don't understand why Microsoft distributed such a "special" windows update to their Surface product.


    After using SP4 for a while, the CPU stays at 2.90GHz always. Nothing helps to solve this problem. :(

    I had the same problem and it was solved by re-installing the update via the Media Creation Tool:

    You do not have to create a USB stick, only execute the tool to update your device.

    Did you wipe everything and reinstalled windows from scratch? Or did you keep your existing installation and only re-applied the update on top of it?
