Windows 10: CPU throttling stuck at speed far beyond what was considered minimum for Win 10 in 2015

Dear Microsoft,


I don't think you are capable of creating hard- or software ... not to mention creating a working combination of both. I was using Surface Pro since version 1.


There has been a Surface Pro 4 with i5 and 8GB RAM for some years now but had to face the fact, that as soon as I was running just 2 or 3 applications like a browser, an IDE for developing a web application and a service that's providing that application for local preview was exhausting those 8GB of RAM. Even after start the idle load was at 3 GB RAM.


Thought I might have to switch for another device, so there has been a Surface Pro 6 Business with i7 and 16GB of RAM for some days now. But starting yesterday I'm facing new issues. This time it isn't the RAM that's exhausted or the CPU load, but some fancy stupid software component that seems to having issues with controlling resources properly. There is a decompression running in background, trying to extract a 2 GB archive just downloaded. But the system doesn't seem to think about rising CPU frequency again. The device is in docking station with its lit power LED indicating proper plugging.


There is no CPU load, currently. It's beneath 10% most of the time. Same applies to RAM, even though it's at 50% currently. There is plenty of free space on SSD (around 270GB). But the system is lagging like hell, even after restarting in such a situation.





According to task manager - which takes up to 10 seconds to compile its initial view - the super-fancy 4-core i7 is stuck at 0,40 GHz ... let me translate this into 400MHz ... is Surface Pro 6 your current device or some new housing for a Pentium-II system built in mid 2000s? Maybe this is due to your new Win 10 1903 I was urged to install recently.


Please, don't just distribute ALM tools, but use them as well! For several days now I have failed to work for earning the money you want me to pay for this stuff because your business-grade devices aren't worth that money.

CPU Throttling after Windows 10 Anniversary Update

Apparently Fall Creator even goes further with CPU throttling or more defined its supposed to limit CPU access for apps running in background. But I feel laptops are suffering from more then just background apps throttling CPU use. My laptop is slower
to boot, opens apps slower and just feels like CPU is really throttling back. I ran Task Manager and it does appear it takes a lot of demand to get the CPU up to its rated clock speed. Many users have found that Fall Creator makes all but the balanced profile
in Control Panel power as hidden and I think this is to aggressively de- rate the CPU to brag about how Fall Creator saves battery. Well yes, it may indeed save a bit more battery, but at the expense of performance. A work around is find Mobility Center and
switched your power setting back to performance. This at least sets CPU to its max clock speed. The other option is go into advanced settings in power profile and set CPU minimum percentage back up so it does not reduce clock speed so much. This is not just
affecting lower class CPU's but my wife's i7 7500u was affected and caused the laptop to run slow. My wife is not that in tune to changes in performance but she definitely noticed the speed reduction.

 

CPU Throttling after Windows 10 Anniversary Update

After an automatic (without asking first) upgrade to the Windows 10 Anniversary edition, my computer started running slowly. I assumed it was probably a typical software problem (e.g. far more time expended in security activities), but then I looked at the
Task Manager performance tab and noticed that my 2.4GHz-rated CPU is running at 0.60 to 0.79 GHz. It would normally show both baseline and boosted speeds up to 3.0GHz.

I find it a bit much to believe that, coincidentally, exactly when the update arrived, my fan or heat or CPU failed (note that my CPU is running from 41 to 54 degrees centigrade, which is not terribly cool, but FAR from the 100-degree limit). I think it
more likely the new OS is somehow telling the CPU to throttle itself.

Can anyone else whose system is running like dog droppings after the upgrade check to see if their CPU speed has dropped?

 

Win10 CPU Throttling

Win10 appears to throttle the CPU down when it gets too hot. This is probably a good thing (I figure it prevents the CPU from melting down). It seems, though, that Win10 doesn't seem to recognize when the CPU has cooled back down, so the CPU remains in
a throttled-down mode indefinitely. I haven't figured out a way to reliably get Win10 to reset the throttling. As a work around, I have downloaded ThrottleStop which allows me to override Win10's behavior. Of course, I now have to manually watch the temperature
to ensure that the CPU doesn't overhead, but it's better than having an unusable CPU. Is anyone aware of a solution to reset Win10 throttling so that I don't have to use a third-party product to do it? Better yet, has Microsoft acknowledged the issue and
provided any guidance on when this issue might be corrected?

In case it matters, I am using a Dell Laptop E6410 with an Intel Core i7 M 640 CPU.
