It's the procces that connects your iPhone, if you have one. Not dangerous, but not needed if do not own an iPhone.

Appeared after installation of iTunes
distnoted.exe is installed along with ITunes, and it will be a running process in your tasklist if you are using IPhone
must be iTunes related too
Spawned by AppleMobileDeviceHelper.exe, which is spawned by iTunes.exe. If closed, it will be rerun automatically.
Virus that fakes the certificate of an Apple program and prevents iDevice from being disconnected.

belongs to iTunes . Potentially a Trojan - it behaves like one .
opens with iTunes.. killing process is not dangerous but not necessary
used for itunes
Makes me crack up when this previous user says part of iTunes but it's a trojan. Don't think Apple wants to spread stuff that kind of stuff. Relex people don't be so paranoid!! :)
Installed with iTunes. You don't have to remove it.
It is a iTunes process, anyone who thinks otherwise is a fool. However, this is not required for iTunes to run
It's a trojan, it installs a process that allows Apple to track your every moves thanks to the integrated GPS in iphones.

distnoted.exe is NOT a trojan. It is part of the i-Suite of software distributed by Apple. Not needed to run iTunes, but it helps integrate i-devices with your PC running iTunes. Anyone saying it is a trojan obviously do not understand what a Trojan truly is. Apple CAN NOT collect your data using this program.

it's an essential component for iPhone communication via iTunes. No need to remove it or be worried about it.
It is from apple.

Runs if you use an iPhone with iTunes on your computer. Not important for Windows, but iTunes will restart it if you turn it off.
If you kill it and connect your iPhone, it will re-start.
Required by Itunes for Iphone.
it's annoying

An Apple Software Program, not informed about during install of any part of there software, intended to track information passed between on your PC and your iType device.
itunes/iphone related
In order to connect your computer to the iphone, you need this. Removing it will get you only an error message and a re-install from itunes.
It's not a trojan. It's essential for connecting any iDevices and iTunes. iTunes creates MobileDeviceHelper (AppleMobileDeviceHelper.exe), which then creates distnoted.exe- It's not essential if you don't use any iDevices, and it's definitely not anything suspicious or dangerous. It's also explained on the official Apple kb article (linked to at further information).

I don't know anything about it except that it is taking 25% of my CPU process and I'm not running iTunes or have any iPhone connected. On Windows 8.
  Jeff C.  
slows down the CPU a lot sometimes

Best practices for resolving distnoted issues

A clean and tidy computer is the key requirement for avoiding problems with distnoted. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the distnoted.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
