YSloader.exe and distnoted hogging CPU

Hey,

got to:

C:\Program Files (x86)\Common Files\Apple\Apple Application Support

look for distnoted.exe and right click on it. on the compatibility tab (click change setting for all users if you have that option); then check run this program in compatibility mode for: and select windows 7. also check run this program as an administrator. click apply then ok

This seemed to fix the problem for me....let me know if this helps

Did you try connecting an ios device and syncing it? Making distnoted run as an administrator will cause it not to run. That seems to be ok as long as one doesn't actually try and sync. In that case, YSLoader (SyncServer) will still loop regardless of distnoted... at least for me.

Are you running 32 bit Windows 8.1 or 64 bit? I don't have a problem on my 64 bit Windows platform so there might be a difference there. But my 32 bit Windows 8.1 will have Syncserver looping even if distnoted doesn't run...

I have a similar problem for Windows 8.1 32bit. The method described above solves the problem for distnoted.exe, but not for YSloader (SyncServer.exe). Attempts to apply such changes to the application SyncServer.exe have not given results.

I am using iTunes on Windows 8.1 Pro 64 Bit and have same issue. After using the fix from esivue distnoted.exe doesn't load anymore and YSloader.exe is still using around 30% of CPU...

This worked for me on Win 8.1 64-bit and Kaspersky Antivirus 2015 (no problems syncing, etc.):

1. Go to C:\Program Files (x86)\Common Files\Apple\Apple Application Support

Set compatibility mode for distnoted.exe to Windows XP Service Pack 3

2. Do the same for SyncServer.exe in C:\Program Files (x86)\Common Files\Apple\Mobile Device Support

... and any other iTunes processes if they will hog the CPU (I only had problems with these 2 so far).

Then you aren't using UAC - putting the files in XP compatibility mode prompts if you have UAC on. However, since a subcomponent of a program cannot prompt, the component just doesn't run. I certainly wouldn't recommend anyone turning off UAC just so they can run iTunes properly!

I did not disable UAC. Don't theorycraft, try it out yourself.

It did not work for me as I reported here last year. At that time, ysloader was causing the problem and was essential to synching. Apparently, it doesn't work that way with the latest version so the fact that these programs never run (I've verified that they don't) when in compatibility mode *appears* to be benign. But it is a little unsettling to know that two programs which normally run aren't running (verify this for yourself with the task list manager).

I had problems with distnoted and syncserver, not YSLoader. They might have changed something in recent iTunes or Windows update. I suggest to try again if you haven't recently. According to Russinovich's Process Monitor, syncserver.exe indeed doesn't do as much as it does without the "fix", it seems to practically just load and exit, but for what I use iTunes for (playing music, syncing music with iPod), I have no problems so far and no CPU hogging.

The proposed "workaround" with changing file settings for distnoted.exe and syncserver.exe is only a partial workaround. As JAta2 already mentioned those changes to distnoted.exe and syncserver.exe will cause that both programs won't run. It's not important to select any specific compatibility settings as long as you change them to "run as administrator" for all users. Since both programs won't run at the next device synchronisation, there won't be any high CPU load. However, this only allows to synchronise music and play-lists. Eventually it may be possible to synchronise with this workaround ebooks, videos, pictures too (I haven't tested it). Definitely this workaround does not allow synchronisation of any Microsoft Outlook item, like contacts, calendar and notes. For those distnoted.exe and syncserver.exe have to run.

In addition for certain situations its also required to apply the same change to MobilDeviceHelper.exe.

Tested on: Windows 8.1 Pro 64 bit with Kaspersky Internet Security 15.0.2.361c and iTunes 12.2.0.145.

I still hope Apple will fix this problem - maybe for a Windows 10 update of iTunes.

I can confirm that the problem still exists on Windows 8.1 Pro 64 bit with Kaspersky Internet Security 15.0.2.415(c) and iTunes 12.2.0.145.

distnoted.exe CPU hogging Problem still exists on Windows8.1 Pro. I don't understand why Apple don't fix that in recent Itunes updates.
