Windows host process (Rundll32) HIGH CPU usage

    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 itís 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 youíve installed like games or application update (if you donít care of the updates of cores).
    If you enable at least the windows section (without internet explorer section and etc.Ö) 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.
