Hi, I'm John! I will help you with this.

You usually don’t need Bonjour unless something is actively using it (like iTunes, Apple services, some Adobe apps, or network printers).

Why are you checking this? Are you planning to remove Bonjour?

Are you getting any pop-up or error message, especially something mentioning ndnsNSP.dll?

Welcome Douglass Cann,

Thank you for reaching out to Microsoft Q&A forum. I am here to assist you.

To help identify the fastest resolution, please confirm the following:

Have you noticed a specific app or feature on your PC that stopped working and may be related to Bonjour?

In the meantime, you can review the following information to understand which programs commonly rely on Apple Bonjour on Windows systems:

Option 1: Apple-related software

iTunes (for device discovery and shared libraries)
Apple Music for Windows
iCloud for Windows (limited network discovery features)
QuickTime (older versions)

Option 2: Printer and scanner software

Network printers, especially older HP, Canon, Epson, and Brother models
AirPrint-compatible printers installed on Windows via vendor drivers

Option 3: Media and streaming applications

Adobe Creative Cloud apps (device and service discovery on local network)
Some versions of Adobe Photoshop and Illustrator
Media servers and streaming tools that auto-detect devices on the same network

Option 4: Smart home and IoT software

Control apps for smart TVs, speakers, or media boxes that rely on local network discovery
