itunes is using 100 % CPU

Going back to 10.3 is no solution though.

Did you try the msinfo32 thing to see if you have any 3rd party network providers installed?

I just installed Itunes 10.5 on my XP computer and have the same issue - 100% CPU and was taking over 10 min to copy 1 song from a CD to my library. This new Itunes version is pathetic. Apple needs to provide a fix for this

APSDaemon was taking 100% CPU after itunes 10.5 installed on Windows XP SP3.

There is a conflict with NetNanny described on their forums:

"With Net Nanny installed and not running iTunes, login to Admin Tools, click on Exceptions and Application Exceptions then select custom and enter the executable and try again."

(The executable being APSDaemon.exe)

This fixed it straight away for me.

**** it, Apple! Thanks to your latest iTunes software update (10.5.1.42), you've not only rendered my iPhone 3G incapable of syncing to iTunes on my WinXP SP3 machine, but now your **** iTunes and Apple-related software consumes 100% of my WinXP SP3 PC's CPU resources.

I've completely uninstalled and clean-reinstalled anything related to Apple software on my WinXP machine a bazzalion times but to no avail, it still doesn't fix the 100% cpu utilization problem!

In reading the forums here, it appears that i'm not the only Windows PC user suffering from this problem resulting from the latest 10.5 release of iTunes. Frankly, Apple is really starting to **** me off enough so that i think it's finally time to get rid of that iPhone, which literally costs me twice as much monthly with AT&T as i'd be paying if i moved on to an Android-based, smartphone.

You guys at Apple really need to get your act together!

Ok, so here is the fix, at least this is what i did and it worked for me:

Step 1: Uninstall everything related to iTunes, QuickTime, Bonjour, Apple Device Manager, etc. Follow the instructions PRECISELY as indicated at this URL: http://support.apple.com/kb/HT1925

Step 2: Verify that all Apple applications indicated are completely uninstalled. Follow the instructions indicated at this URL: http://support.apple.com/kb/HT1925 Manually delete all the various folders and their contents indicated. In my case, i actually could not delete the Bonjour process and its folder because the mdnsNSP.dll in the remaining Bonjour folder kept starting up despite the fact that it had been presumably uninstalled. If this is the case, Windows will throw an error message telling you that the file cannot be deleted. To kill this file in my case required that i manually rename the existing mdnsNSP.dll remaining in the Bonjour folder to mdnsNSP.old, (an old trick i learned years ago!) and then reboot. AFTER rebooting, I was then able to finally select and delete the entire Bonjour folder and its contents as required.

Step 3: After rebooting in Step 2, open a command window and at the prompt, type the following command: netsh winsock reset This will reset the winsock stack and cause the running Bonjour process to unbind. After doing this, reboot the PC again!

Step 4: After the PC reboots, reinstall the latest version of iTunes. In my case, it was version 10.5.1.42. At the final stage of the iTunes installer, DO NOT select the option to finish and start iTunes. Instead, uncheck the box that says to finish and start iTunes and then click on finish. After doing this, reboot the PC. After the PC reboots one final time, ONLY THEN fire up the new install of iTunes for the first time, and voila, the 100% consumption problem should now be fixed!!

Hope this helps the millions of WinXP iTunes PC users who continue to suffer from the aforementioned iTunes 100% cpu consumption issue!!

Happy Holidays!

I've tried everything....I have AVG family safety and have it disabled.

But Apple cannot seriously expect people to remove monitoring software for people to buy the entertainment it offers.

It's amazingly arrogant.

In the old days, Microsoft was too big to care. Now it is Apple. Sure, I can take my business somewhere else, and there are cheaper alternatives to the I-Stuff now. Apple won't cry for losing me.

But being treated like crap, having to choose between protecting my kids and the entertainment offerred by Apple is offensive--and after buying into their proprietary formats.

Appalling.

(I wonder what words I need to use in this post for Apple's bots to flag this comment as one they might actually read, because otherwise, we're all just pounding sand anyhow)

I just went to the "Store" tab in iTunes and then clicked "sign out" and it seemed to work pretty good.

I resolved my problem by going back to itunes 10.3. Same symptoms as described above. 100% CPU usage, Win XP SP3, won't go to itunes store. Tried the uninstall - reinstall and netsh winsock reset. Neither worked. Tried to remove any non standard protocols but unable to find their source. Have no net nanny or any other AV software for that matter since I only use the computer for music. Clearly, there is something messed up with Apple's 10.5 release if the same machine with the same software workes wonderfully with 10.3 and works misearably with 10.5. However, as many above have indicated, Apple seems not to give a #$%&*.

I have no problem downloading MP3s from Amazon! 😁

I don't know if there is a way to configure AVG to allow iTunes or apsdaemon through, like you can with NetNanny's exception list as I just uninstalled NN. Worth asking AVG though.

It is totally ridiculous though. ITunes is clearly not recovering well from failed socket connections.

How can a failed socket connection affect 10.5 but not 10.3 ???

Assuming that's a serious question, for a start 10.5 introduced wifi syncing so I assume that at the very least there is a new service for that which has to bind to a network socket. The iCloud stuff might use new protocols too, I don't know. Someone could have even screwed up something in 10.5 that worked fine in 10.3 while just maintaining some old code. Maybe they were trying to make iTunes not the most clunky, least responsive piece of software in existence, I don't know. The fact it screws up the Store and I think also the iOS5 upgrade online verification step makes me suspect it's deeper than just the wifi sync.

Whatever it is, it should fail gracefully when it can't attach to a socket properly and it clearly isn't hence the CPU usage at 100% with no error or any other indication something isn't working.

I uninstalled 10.5 and installed 10.3. When Itunes started and tried to access my library it gave me an error that my library was from a later version of Itunes so it would not let me access my library with the 10.3 version so i had to uninstall it.

I tried following your instructions and no luck. WHen I resinstalled Itunes after removing it and following step 4 i get the error: Unknown Error 42408 when it tries to access the Store and it is still running 100% CPU

If you went back to 10.3 then you can simply delete the itunes library file (itunes library.itl) and it will recreate it. You will lose playlists but you may be able to back those up first before you go back to 10.3. I did not have many playlists so it was not a big issue for me. There is an apple article here: http://support.apple.com/kb/ht1451

My solution on XP was to remove the APSDaemon startup entry from the registry and stop it in the task manager.
