    Why is my CPU on 50% when nothing is running


    I was wondering why my CPU is on 50% when nothing is running. this is been doing this for over a week I don't know why but I think it's because my laptop was on all day. or maybe it's because I was downloading a big file. and also it really affects when I am playing a game . is there any solution for this?. That's all

    :)

    AppleMobileDeviceService.exe consistently takes 50% of CPU usage.

    Original title: An App. called AppleMobileDeviceService.exe consistently takes 50% of CPU usage. I am not using iTunes. Apple says iI should ask Microsoft. I use AX oper. sys.

    An App. called AppleMobileDeviceService.exe consistently takes 50% of CPU usage. I am not logged on to iTunes, nor is my iPod connected to my PC when this .exe runs with 50% usage. Apple suggested I contact Microsoft. I use AX oper. sys. Apple suggested
    contacting Microsoft.

    wsappx is using 50% of the CPU

    Hi,

    Wsappx is a Windows Store program that is trawling your computer for all installed apps and telling Microsoft what programs you have, what versions etc. If it’s using more than 50% of your CPU and causes trouble on your
    device, we would recommend that you disable it. You may follow these steps:

    • Go to Control Panel.
    • Look for Administrative Tools.
    • Select Computer Management then Services, you will see this entry:

      Windows Store Service (WSService) "Provides infrastructure..." [Status is blank] "Manual (Trigger Start)" "Local System"
    • Now you may disable it.

    Feel free to contact us if you have further inquiries.

    Why is my CPU on 50% when nothing is running

    Problem: Explorer 50% cpu usage


    Every day, at intermittent times unrelated to anything I do [it happens when I'm doing nothing], Explorer starts running with each core at about 50% cpu usage, and does not stop. Temperatures and fan speeds rise, fans become very noisy.

    Speedfan indicates core temps rise to ~ 70 degrees C, "Temp1" rises to 75 - 80 degrees, fan 1 speed ~ 4000rpm,
    fan 2 speed ~ 2500 rpm.

    I have just installed Windows 10 so it seems it could not be caused by a virus/malware.

    In windows 7 forums some users found the problem was caused by a corrupted file:

    Explorer.exe 50% CPU usage - Windows 7 Help Forums

    Since my problem is intermittent is it unlikely to be caused by a corrupted file?

    I can't use the solution suggested in the W7 forums because when I kill explorer I lose my desktop.

    I ran diskcheck on both my hard drives and it reported no errors found.

    Any suggestions would be welcomed.

    Can someone please explain why a corrupted file would cause explorer to run at 50% cpu usage?
