apsdaemon.exe

One more possibility ... Standalone QuickTime Player install? (It's like iTunes or Safari, also requires an AAS install.)

Didn't think of that one. Yes, that's certainly a possibility. If I'm feeling ambitious one of these days, I'll do an erase and install of Win 7 and then apply one thing at a time, starting with the gray disks the Mac came with, and see when that .exe appears. Though even that may not be definitive as it may be in more than one update.

I unchecked it in MSCONFIG so it doesn't load at start up, nor does it load when I open iTunes, but it DOES load at some time, but I can't figure out when.

That seems consistent with what I'm seeing, Peter. It's in my MSCONFIG startup items (as Apple Push), and ticked. But the process isn't running after a restart. So it seems like it only runs when something calls on it. I'm not sure what calls it either.

It's an internet/network application based on the info Kurt has supplied ... do you have a rule set up in your firewall software allowing it full access to the internet? (On occasion, trouble with firewall rules can cause processes and applications to run at loathsomely-high CPU levels.)

🙂 Ta, Kurt. (If you have a spare few hours sometime ... )

There's no official list anywhere I'm aware of of the Apple installers that also incorporate an AAS installer. We have to make it up out here in the Gamma as we go along. iTunesSetup.exe, iTunes64Setup.exe, SafariSetup.exe, QuickTimeInstaller.exe: definitely. I'm not sure about the MobileMe control panel ... it needs AAS to run, but I haven't ripped open a MobileMe .exe-based installer to see if there's an AppleApplicationSupport.msi in there. So it's interesting to know both whether there is or isn't an AAS in any given Apple Software installer bundle.

I also found this problum when I updated to iTunes 10.5.2. The cpu possess around 50%. Now I just untick two option , "Sync with this iphone over wi-fi" and going to "edit"--"preference"--"store"--untick "Always check for available downloads". It seems that the problum is no loger happen.

Anyways, I hope Apple can fix this problum as soon as possible.

oh,I'm wrong , It seems that even I unticked those two option, as first it is nothing happened , but after 15 or 20 mins later, the cpu is still prossess 50% again .Only close itunes retune normal. What are annonying iTunes .

Hope apple release new version for fix this bug.

If anyone is still having this problem, I've just encountered it myself maybe 5 minutes ago and found my own little fix... If you don't want to completely shut it down, or remove it from startup, you can simply lower it's priority over other processes.

To do this, just open your task manager and find the process. Then right-click and go under "set priority" and set it as low as you feel you need (I set mine on "low" the lowest setting possible). Now it should run properly, but when you try doing other tasks the computer simply pushes that process to the side untill it has the resources to get back to it...

This is working fine for me, and I hope it works for anyone else that seems to be having this problem.

A (dumb) question and a (not-so-dumb?) suggestion:

Can someone tell me how to get to the "synch over wifi" setting? I can't find it under any of the tabs under preferences, or anywhere else in iTunes. And their help is less than useless.

And here is a suggestion for those who have tried everything else. If apsdaemon.exe is not needed, why can't we replace the .exe file with something harmless, like notepad.exe? Then every time Apple wants to start this piece of ^&*$ you end up with a notepad window that you can just close and keep working. RealPlayer always starts an "auto update" daemon every time you launch it (and worse, it adds it to the startup list on msconfig). So after a while I got sick of it and replaced the .exe with notepad.

After the latest update failed to fix this issue, I decided to take more drastic action. Since I don't use the wifi sync option, I decided to prevent the process from running. Rather than delete the file, I tried something easily reversible by changing the name. I went to "C:\Program Files\Common Files\Apple\Apple Application Support", found APSDaemon.exe, and changed the filename to APSDaemonX.exe.

Now APSDaemon never runs, and there have been no errors or other ill effects from iTunes so far. I expect I'll have to repeat this procedure every time I install an iTunes update if the problem hasn't been fixed.

I've also been struck down with this problem and renaming APSDaemon.exe is the only way I can get iTunes to run. Fortunately I don't wifi sync so no real loss.

Just for future reference: people running Windows having problems with startup programs - there is a great free program called Autoruns (you can download from filehippo) that allows you to adjust which programs start at boot time, and is much easier to use than msconfig.

Just a quick tip if making changes to the HKLM\Software\Microsoft\Window\CurrentVersion\Run section of the registry... those entries are paths to a file eg:

APS Daemon

C:\Program Files\Common Files\Apple\Apple Application Support\APSDaemon.exe

Instead of deleting the registry entry - and possibly stuffing up... all you need to do is place a character at the start of the path value... the OS will not be able to find the file if the path doesn't exist - windows then ignores the entry and moves onto the next one.

When making changes to the registry I enter the text - not used - at the start of the path.. so it looks like this:

not used C:\Program Files\Common Files\Apple\Apple Application Support\APSDaemon.exe

If you find you need to reestablish the line in the registry, it's much easier to remove the "not used" than it is to recreate the entry all together, and get it correct... also "not used" stands out in RegEdit quite clearly - so you can quickly tell the entry has been disabled intentionally.

If you dont have the msconfig entry you can always delete it from the registry

Type 'regedit' to go to the registry editor.

I believe the key you would need to delete is

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\APSDae mon

obviously the usual disclaimer about being careful when deleting from registry, irreversable etc applies and you should back up the key first in case you need to put it back.

I continue to have persistent problems with APSDaemon.exe. I'm on an older (relatively) Windows system, a Dell Inspiron E1505 running Windows XP SP3. It just barely has the memory resources to do what I need to do. And now, with the latest version of iTunes, APSDaemon.exe comes along and hogs them. It constantly and consistently takes up 50% of my CPU. Usually, when I'm not doing anything CPU-intensive, I don't notice a huge problem with this. But sometimes it really gets burdened.

I have read this thread, and tried a number of things. APSDaemon.exe is not on any of my startup queues, in the registry or anywhere -- I've run the "Autoruns" utility and checked. In fact, in poking at things with that I completely crippled my system, killing something I should not have killed, and was fortunate that Windows could revert to my last successful configuration.

APSDaemon.exe seems to be part of iTunes that starts whenever iTunes starts. I tried removing or renaming the executable, as others have suggested here, and my iTunes complained that it was missing something and couldn't run. I use iTunes, so I had to restore it.

I don't have any interest in wireless sync, and wish I could completely disable this. I do, however, access my iTunes through the Remote application on my iPad -- does this also utilize the Push service? In any case, I wish Apple would notice this problem we're having and do something about this CPU hog -- make it optional to disable it or make it more respectful of older systems.

After verifying that I can kill APSDaemon every time it starts without it affecting iTunes, I just overwrote the .exe file with something harmless. You can use, for example, C:\WINDOWS\system32\notepad.exe and then every time iTunes tries to start APSDaemon, you get an empty notepad window that you just close. It's a bit annoying but it works. Or you can find other executables that are even less visible.

I have a toolkit called MKS wich simulates unix commands. I overwrote APSDaemon with a program from that toolkit called touch.exe which simulates the Unix "touch" command. It pops up a DOS window for a few seconds, then it goes away and iTunes keeps working.
