APSDaemon.exe uses excessive CPU resources

On my dual-core WinXP system, APSDaemon.exe (the wireless sync service) regularly uses all the cycles on one CPU (it runs at 50% CPU utulization in Task Manager). If I restart iTunes, the utilization drops to zero for a while, but soon rises back up. I have iTunes 10.5.2.11, and "Sync over Wireless" is disabled for my iPhone. I also connect a shuffle and a nano, but neither supports wireless, so they shouldn't matter (shouldn't...).


I've disabled automatic start of APSDaemon at boot in my registry but iTunes starts it when it runs anyhow. So I've renamed the .exe file, an inelegant solution at best.


Sadly, Apple doesn't let me report this as a problem, so I'm reduced to complaining here. I expected better of them.


Ideally, we should be able to turn off services we don't want to use, like wireless sync, so we can reduce iTunes' bloated footprint. And when they are enabled, but not in use, they should sit there quietly, of course.

To whom it concerns.


Reading this post reminds me to a similar issue with Panda software: 50+ percentage CPU load of the so-called pavjobs.exe file for no reason. Then I stumbled upon a very elegant solution for the Panda issue: add the annoying, non-critical, non-windows-required CPU eating file in list of quarantined files of the antivirus software (don't delete it, not needed). Guaranteed to stop any action at all. And the beauty of it is: in the end Panda itself solved my problem. And so it did for the APSDaemon.exe file. It has stopped and has never returned since.

Hi all.


After having issues with the APS Daemon eating CPU n MEM....i googled up:

You can either downgrade to older Itunes version ( provided you have not formatted your pc recently). Tutorial found on Youtube.


Or


You can simply do a Search for Daemon; APS in Windows, i deleted the APS.exe file.



CPU usage came down from 70% to JUST 9%!!!!





😁 Im happy now!

Okay so I have a Windows 7 Pro, AMD Quad Core. I have 2 iPhone 4s, a new iPad, iPad 2 and iPad. All of them are wireless syncing. I dont have the high CPU usage but I have super high memory use. When I look at the processes, I show APSDaemon 2 times. Each use almost 320,000k!

So If Im to understand the posts so far, these processes have nothing to do with wireless syncing to devices????

My APSdaemon.exe issue coincided with the same issue from the AppleMobileDeviceService.exe process.


The problem for me was not resolved by iTunes or iCloud uninstall/install (iCloud uninstall or even logoff at a PC is risky for your Outlook data by the way).


The solution was:

- OPEN Command Promt with Administrator’s privileges and

- run:

netsh winsock reset

then

- reboot Windows.

Hm.... it seems people are still having issues - and as a matter of fact so do I, despite my happy announcement above...

I no longer have the original problem with APSDaemon.exe using all CPU ressources - but now iTunes is just plain unstable, half of the time it won't detect my iPod, and then I can only make things normal by terminating iTunes in task manager and rebooting Windows. If I don't reboot and just relaunch iTunes it will promptly hang.

I have a newer computer running Windows 7. Since APSDaemon.exe was added to my startup, it has been screwing up the way other programs started up when booting up. I ran autoruns in administrator mode, clicked on the logon tab and unchecked the APSDaemon box, to prevent APSDaemon from running on startup. When I rebooted, the computer booted the way it had before the update. Since iTunes continued to work properly, I knew it was safe to delete the entry using autoruns in adminstrator mode


If you don't have autoruns, you can get it here...

This is terrible. I ultimately ended up deleting the process, as I don't do any mobile syncing with my 3rd Gen Nano 😀


But still - how can Apple do this? I absolutely HATE using Apple programs on my computer. First, they make you install all these other Apple programs that come with it. I don't want to have Apple Software Updater on my computer. I don't want QuickTime. I don't want Safari! There are also tons of bugs with using iTunes while on Windows 7 - bad interaction w/ Windows Aero and other aspects of the OS. I wish that Apple would do more testing.


Sorry for the rant :/

hi all i'm new to all this.. and the daemon thingy was really bothering me.. i hate when the fun go crazy for nothing.

i tried to go to the process while it was killed in taskmanager... i'm on win7 64 btw... as administrator i set compatibility to win xp service pack3.

well, set like this daemon.....exe ask for uca if you start it by double click, while if you start itunes it doesn't start anyway animore.. so i do not know for what daemon...exe is usefull but my itunes works smooth ans sync nice without it running. so i do not have crazy fun animore..

any hint on the utility of APSDaemon.exe ?
