Hello,

I have recently discovered that my laptop cooler was going crazy and I didn't knew why, then I started Task Manager and there it was "Windows host process (Rundll32) eating 30% of the cpu.

Notebook specs:
Cpu: Intel Core i5 3210m
Ram: 8gb ddr3 1600mhz
OS: Windows 8.1 x64 pro with the latest update

Does anyone know how to find out how and/or why is it doing that?
Thanks in advance.

I added the requested info @arachnaut

Can you enable the Process name and Command line to the column list - that will help.

AEINV.DLL

Is part of the Customer 'Application Experience Program'.

Maybe you should opt-out of that?

Don't know how that option got checked, I would never opt in customer experience programs.
Found it here:
Control Panel\All Control Panel Items\Action Center\Change Action Center settings
I changed it, and I will set the thread as solved if the problem disappears.

Thanks again for the help :D

The results are good. I've basically used the same software in the same way and the problem never appeared again. After I changed that option I had to do a reboot, btw.

Hi there! Having the similar issue.

After about 5-7 minutes of idle, windows host process appears eating 15% of my CPU (i7-3770). Don't know whether the issue did appear on my previous CPU (i3-3220) - I just started noticing on new CPU that the cooler began produce much noise when my PC is idle.

In my case the process is "rundll32.exe aepdu.dll,AePduRunUpdate". Sorry, but I cannot attach the screenshot, because as soon as I press PrtScr, the process disappears.

Having Windows 8.1 Pro Russian.

Also don't know if the solution of @ONEoo7 helps, but I can't find "Action center" in my localized version of windows. I have only "Windows Update center" ("Центр обновления Windows"), "Support center" ("Центр поддержки"), "Sync center" ("Центр синхронизации"). Can anyone attach a screenshot of a mentioned "Action center" so I could find it visually? Maybe it will help.

rundll32.exe is usually used by bloatwares. Try disabling Startup Programs. My highest usage is 97.8% because of Cinema 4D, but never reached 10%+ with rundll32.exe.

I have this issue too. I solved it by performing these steps:
1. On windows 8.1 go to Charms -> Search. Enter "Schedule tasks"
2. In the Task Scheduler window in the left hand pane expand "Task Scheduler Library" and go to Microsoft > Windows > Application Experience
3. There should be 4 entries. The offender that causes the high CPU usage is "ProgramDataUpdater". You could disable it as some have recommended, however I opted to configure the task to kill it self if it runs for more than 1 minute:
a. Right click on "ProgramDataUpdater" and go to properties.
b. Go to the Settings tab. Ensure that the box next to "Stop the task if it runs longer than." is ticked (checked).
c. In the drop down selection box, simply type in "1 minute" (or other time limit). Then click OK.
I did this a few days ago and haven't experienced this issue since. I'm thinking about pushing it to 2 minutes to see what happens.

At least this way if you install another Microsoft program that uses the application experience the issue won't come back. It will always kill itself if something goes wrong.

Your directions were spot on. I just got a new laptop and the CPU was constantly around 30% and and the amount of heat was high and the computer was quite warm. It would drop to less then 5% occasionally but would always return to over 30%. The fan was constantly on "overdrive". The minute I did all the changes outlined above the CPU returned to normal. Good job!

THANK YOU!

Hi. I came by your post searching the Internet for help since I am having a similar problem. My system is running on Windows 8.1 (64-bit). In my case the process that is using a lot of CPU (25-28%) is Host Process for Windows Tasks. I've tried your method but in the Task Scheduler Library I don't see "Microsoft > Windows > Application Experience".
What I have there as Running Tasks is : Cache Task, MsCtfMonitor, System Sound Service and System Task. What can I do stop this Host Process for Windows Tasks from using like 1/4 from my CPU? Thank you.

Thanks for this thread, was driving me mad as well, though for some reason no matter what I searched in charms it wouldn't find anything, even searching Task scheduler found nothing??
Eventually found it in control panel>administrative tools>task scheduler.

Another odd thing, I was initially getting aeinv.dll consuming cycles [one core driven to 100%] but when I checked control panel>action centre>change action centre settings>customer experience improvement program [is that the right place??] it was already set to No.
Then I installed a program which got aepdu.dll on the hop, but I never saw aeinv.dll again and still haven't even after disabling aepdu.dll
aeinv.dll would always kick in after about 4 mins of inactivity or 10 mins after a restart.

Yet another odd thing, I have left aepdu.dll running for over an hour and it never gives up, same with aeinv.dll....I mean....what the hell MS!!
No wonder laptops are blowing up and killing batteries!!

Hi guys,
I had also the problem but I solved with another way, so if you still have it my solution will probably help you :)
So it’s real easy, the problem could be cause if you us Ccleaner (or any other program) and disabled lot of startup application. People think that if they disable startup application there system will run faster but sometime the opposite arrive. So enable everything you disabled and let only the application you now and you’ve installed like games or application update (if you don’t care of the updates of cores).
If you enable at least the windows section (without internet explorer section and etc.…) the problem should be solved after restarting your computer.
So let me know if I helped or if you need anything else and good luck :)

Sorry for my bad English, I normally speak French.
