    Thank you so much! I even had my PC and I-Pad at the Apple store and they didn't know what to do. This command prompt thing fixed my Windows XP machine. As other people have said, everything runs faster, and now my I-Pad will back up to my PC. It wouldn't for the past two months!


    Thanks Again!

    I have the same problem with my LSp. What fix did you provide to work with Safari browser and Itunes?

    Thank you!!!

    I have the same problem with my own LSp. Please give me a hint of what Safari browser does that  I can't intercept


    Thank you!!

    OK, I have been to **** and back since updating  iTunes to version Basically it hogs 100% of your CPU. I read all the articles and forums I could find and tried out everything including Win socket resets, re-installations etc. Nothing worked. My objective is purely to get iTunes in any version format to work so I can use iTunes again.


    I am now smiling and using iTunes. This is what I did.



    As always, create a system restore point so you have something to restore to in case something goes wrong



    Go to control panel, programs and uninstall the below Apple related applications

    • iTunes
    • Quicktime
    • Apple Software Update
    • Apple Mobile Support
    • Bonjour
    • Apple Application Support
    • iPhone
    • any other Apple related product you can find


    Delete or move any *.itl files (iTunes databases)

    You need to remove these as when you install an earlier version of iTunes it will not be compatible with the newer version


    Clean registry

    Run a registry cleaner. I used the free one as part of the Tweaknow Power pack


    Manual registry clean up

    Run Regedit in admin mode and search for anything Apple and iTunes.  (F3 to do next search).




    Go to and download iTunes 10.1 (64-bit).  I tried later versions but had the same CPU issue (not sure why as I was on the second latest iTunes version which worked find until the upgrade).



    The above worked for me and was done at my own risk. If you choose to try the above you do so at your own risk and I accept no responsibility and liability what so ever.


    I will not be updating iTunes again until I see an official Apple iTunes fix for this issue.

    I just tried this and it worked, but I wasn't logged in as Administrator.  Just reseting winsock did the trick. Many thanks to whomever. I've been without Itunes for some time - Itunes Help was helpless.  Thanks again.

    On a Dell D630, the problem was Wave Systems software from 2007, a "Winsock provider" whose biolsp.dll did not play well with other. Fine on iTunes 10.4, 100% CPU usage on 10.5 or 10.6

    This Wave s/w is for the Dell fingerprint reader and a couple of other security features on the laptop. Uninstalled the Wave Systems through the Add/Remove s/w feature in Control Panel...all better now.

    Hi all,


    I'm using the latest iTunes

    Same problem with AMDS hogging up 50% of CPU Usage.

    Try this:


    I found out that my Speedbit Video Accelarator was 1 of the software that has a conflict with Apple software.

    I tried uninstalling it, and Voila.

    Apple Mobile Device Services (AMDS) stopped hogging up the CPU. I can now sync my iPod.

    Maybe by uninstalling all other softwares that were indicated as a conflict by Apple, this can solve the problem.


    Let's see if this works for everyone else?

    Omg!  This worked like a charm thanks sodaboy!  How did you come across this!  I really hope apple fixes this compatibility issue with windows 7 64bit.   It's a huge headache!

  • Powerlift17 Calculating status...

    A few days back I ran the NETSH WINSOCK REST from the command prompt and all issues relating to the applemobiledevice.exe hogging CPU have ceased.  I am running Windows XP Pro on an old Dell PC.
