If you’re an avid user of Apple’s products, the iTunes suit is a must. And, even though it’s natively used on MacOS, the Windows platform version is quite well optimized and designed. As most of the Apple products indeed are.

However, that doesn’t make this software perfect. A lot of users experienced issues with Bonjour service, the essential part of the iTunes suite. One of the most common errors goes by the ”100” code.

In order to address this, we provided the solution which is commonly regarded as the best-suited. If you’re experiencing issues with Bonjour service constantly, make sure to check out the step provided below.

How to fix Bonjour service error in Windows 10

First, let us explain what’s Bonjour and its dedicated service and why you need it or don’t. Apple isn’t exactly subtle in its approach to iTunes on Windows. Besides the obvious iTunes media library and player, the suit brings various other Apple-related tools and services.

One of those is Bonjour, the zero-configuration network tool. Basically, it locates wirelessly the supported printers and similar devices in order to speed up and ease up the access.

However, as we already know, Apple isn’t too fond cooperating with external OEM’s equipment and thus, Bonjour’s main use is connecting to AppleAir Printer or scarce supported devices within one network. And since there’s a good chance that you don’t use Apple’s equipment with Windows 10, this creates a peculiar problem which is a hard nut to crack.

Namely, for some reason (and in my own experience) it’s quite hard to remove Bonjour service from your Windows 10-powered PC. There’s an uninstalling sequence you’ll need to follow in order to remove it, removing iTunes in the process, too.

Of course, if you indeed use Bonjour, you can install it later on and resolve the service error. Sometimes even updating iTunes fixes the issue. But, as the things turn to peculiar, you can’t remove it for good if you don’t need it.

From my own experience, it keeps reinstalling with the suite update even though you remove it from the system. So, the only thing you can do is disable it from starting up automatically within the Windows Services section.

In case you’re not sure how to do so, make sure to follow the steps below:

  1. Press Windows key + R to open the Run elevated command-line.
  2. In the command line, type services.msc and press Enter.
  3. Locate Bonjour service.bonjour service error
  4. Right-click on it and open Properties.
  5. Under the Startup type, select Manual.bonjour service error
  6. Confirm changes and restart your PC.

That should resolve the ”100” error within Bonjour service and get you going. In case you have a better alternative, feel free to share it with us in the comments section below.
