For what it is worth, my Windows 10 box is using the "High Performance" power profile. I've always used this in the past and the processor would throttle down.
This picture shows my Windows 8.1 box working as expected:

This picture show my Windows 10 box with the same settings as above, but not throttling down (ever):

Setting the Minimum Processor Setting much lower will allow the machine to throttle down.

Hi EslamSamy,
The processor is over clocked according to our Intel® Processor Diagnostic Tool. It is necessary to reset BIOS settings or manually decrease the processor speed to 1.9GHz.
Intel Core i7-3517U 1.90GHz
--- Reading CPU Frequency ---
Expected CPU Frequency is --> 1.90
Detected CPU Frequency is --> 2.674
If processor is overclocked by the BIOS settings, the processor is not capable to reach 3.0GHz.
Intel® Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it. It is the maximum single core frequency at which the processor is capable of operating using.
The maximum speed with Intel® Turbo Boost Technology depends on the processor temperature.
---------------------------------------------
Barber107
The Core multiplier is set to 44; The 4 Cores are running at 4.4GHz instead of 4.0GHz. The processor is over clocked. The processor has an internal chip, it will decrease the processor performance as a manner to protect it from overheating.

Mike C,
Here is the thing...my board is not set to overclock the processor. I suspect the issue is how Windows 10 is handling things...or something else strange.
For proof, here are pictures of my motherboard configuration:

Hi Barber,
The Performance upgrade is set as Auto; this setting will over clock the processor, change it to manual. Verify on Gigabyte website if there is available any newer BIOS version for Microsoft® Windows 10.

I disagree about the motherboard overclocking the processor. So I only have the option for Auto or different level of overclocks.
I am running F8 bios and F9 is the latest stable, so I'll upgrade to that and see if it makes a difference.
Here are some pictures of the various settings and what impact it has.

Hi Barber107,
I have a similar problem - just upgraded my inspiron7110 with an i7-2630QM CPU to Windows 10 and as soon as I change windows power options to 'High performanced' or even 'Balanced' the CPU speed goes up to 2.6 GHz and pretty much stays up there - occasionally it drops to a bit less than 2 GHz but only for about half a second and then pops up again to 2.6.
Sometimes just after a restart, however, the OS seems to handle it correctly - freq. nicely moving between 1.9 GHz and 800 MHz, depending on load, and only boosting up to 2.6GHz on heavy loads, but after about 30 seconds Windows switches back into the 'funny mode' and the frequency ist stuck again at 2.6 Ghz.
Did you find any solution to the problem in the meantime? I would be eternally grateful for any clue, cause I'm just about ready to roll back to Win 8!!!
Cheers,
Andre

Hello, I have upgraded to windows 10, and my processor seems to be stuck in oscillating 33-40% of the maximum frequency, even though the CPU usage goes up to 100%. It doesn't seem to respond to windows settings, when I activate the high performance power plan (100%min-100%max processor states) it doesn't change. I have a compaq Probook 4430s with intel core i5 - 2410M. Already run Intel diagnostics and it's OK. The BIOS doesn't have a FSB clock setting and it doesn't have any software that I know controlling the processor frequency manually. How does windows/intel drivers control this? I already installed the Management Engine Driver for Windows 10.

Hi Gabriel34,
Prebuild systems require customized drivers from the laptop manufacturer. I reviewed Hewlett Packard support website and there are no drivers available for Windows® 10. The hardware is not properly recognized by the new operating system.

I am having the same issue. CPU Z shows my brand new 4790K as always running at 4.4GHz (44 multiplier) even though it could throttle down to 800 MHz.
I've only ever ran Windows 10 with this system. I will boot a Linux live distribution tonight to see how it handles things.
Here is my screenshot of CPU Z, Windows 10, and a Passed Processor Diagnostic Tool:

Hello All,
Please confirm with manufacturer if you have the latest Chipset drivers for Windows 10*, https://downloadcenter.intel.com/download/22596/Intel-ME-Management-Engine-Driver Intel Management Engine drivers also check in Power Options and Power plan you set.
If Power saver your CPU will work at minimal clock in balanced he will switch clock, in high be able to run at highest clock based on the Operating System requirements.
Your Processor's Base Frequency 1.9 GHz and the Max Turbo Frequency 3 GHz. Max turbo frequency is the maximum single core frequency at which the processor is capable of operating using http://www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-technology.html Intel® Turbo Boost Technology. Frequency is measured in gigahertz (GHz), or billion cycles per second.
If the Intel® Management Engine (Intel ME) driver has not been successfully installed, you may see an error on a "PCI Simple Communications Controller" in Device Manager.
Additionally, please run https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool-64-bit- Download Intel® Processor Diagnostic Tool (64-bit) and provide the results if possible.
Please confirm these settings and let us know if there are any improvements.
Regards,
Caesar B_Intel.

Hello Everyone - I FINALLY found the solution to my problem. It is the Intel Rapid Storage Technology that is responsible for the CPU running too fast and it takes about half a minute to get rid of the problem: go to task manager, click the tab called Details, sort by CPU usage and the second entry should be "IAStorDataMgrSvc.exe". Right click, choose "end process tree" and the CPU will run perfectly normal. Then click the Start-up Tab within Taskmanager and disable IAStoricon (right-click: disable) and your machine is ready to function normally in Windows 10. Everythingg seems to work perfectly on a first glance but ideally I would replace my Rapid Storage driver with a more compatible one - right now I have version 10,1.2.1004, but that's the only one offered by DELL support. Perhaps someone inlcined and qualified from Intel could help out on this with some advice?
Anyway, I hope this can help a few fellows out there who are struggling with similar Win 10 problems - I'll post an update if I find any replacement/upgrade for the Rapid Storage driver.
Cheers,
Andre

Hello,
on my i5-3570 on z77-ds3h chipset under Windows 10 I also have Turbo Boost enabled all the time when I select High Performance power plan 100-100. When I change to 5-100 or even 75-100 (this is what I usually use), the CPU frequency fluctuates between 1600-3800 or 1600-2900-3800 MHz respectively. Turbo frequency is 3800 MHz base frequency should be 3400 MHz but almost never is. The computer is perfectly stable so I do not need to change this behavior, but I am curious why it works like that. I was thinking that turbo kicks in only when high CPU utilization is needed. No overclocking is done on purpose, BIOS set to auto and base multiplier set to 34.
Thanks for opinion!

Hi jumpingjackflash5,
Intel® Turbo Boost increases the speed of each Core when system requires more processor resources. It will depend on processor voltage and current. The process is automatic it is not possible to customize it manually.
Some motherboards BIOS offer the option to overclock the processor, but this is not related to Intel® Turbo Boost.
I suggest you to reset BIOS settings to default. Make sure the system has the latest BIOS and chipset driver.
The i5-3570 processor comes with Intel SpeedStep® Technology, the speed of the processor can be less than Base Speed while system is idle or using few resources.

Yes I know that Turbo Boost works automatically but I was thinking that it kicks in only when CPU is under load and when idle the CPU is at its default frequency, e.g. 3,4 GHz. In my system it works much like the 3,8 GHz is the top baseline of the Speedstep frequency span. When I choose balanced power plan (5-100 CPU), it varies from 1600 MHz to 3800 GHz, when I choose High performance and do not alter the values (100-100 CPU) it most of the time stays at 3,8 GHz, sometimes goes to 1600 MHz when fully idling. I usually thus set Windows power options to 75-100 CPU, then when idling it sometimes has 2900 MHz.
I have reset/updated BIOS to latest, no changes. Also I think that under Windows 8 CPU was not on 3,8 GHz so often. Maybe Windows 10 chooses power states differently, preferring higher performance especially under some power plans ?
But since I have no stability or temperature problem even when Turbo Boost running more frequently (CPU temp ranging from 45 to 60 C), I have no problems with the described behaviour, I was just curious what is the cause.

Hi jumpingjackflash5,
The processor Base Frequency of Core™ i5-3570 is 3.4GHz. 1 or 2 Cores will reach 3.8GHz with Turbo Boost. Now, motherboards have the option to overclock or set the 4 Cores at 3.8GHz.
I suggest you to set the processor multiplier to 100% in the BIOS, verify if processor speed in the BIOS is set to 3.4GHz.

Thank you for the answer and table, I know that Turbo Boost is supposed to work based on the number of cores. The bios is set to 34 - e.g. 3,4 GHz standard freqeuncy. Maybe it has default option to utilize all 4 cores in Turbo Boost but it is not settable by user. But even if this is true it should afect only the frequency at Turbo Boost, not the fact that Turbo Boost is kicking in under Windows 10 High Performance power plan very frequently (even if CPU is not fully utilized) - seems that the upper frequency range of CPU is extended to Turbo Boost's value.
But as I wrote I have no temperature or stability problems so it can be set this way. I do not overclock specifically in BIOS.
