Usually once per today, while doing nothing, I get the pop up that module is blocked from loading into LSA, and its a folder Bonjour/mdnsNSP.dll.

Does anyone know how to fix this? What is happening. Thanks

    Press Win + R, type services.msc, and press Enter.

    Look for the Bonjour Service in the list.

    Right-click it, select Properties, and then Stop it.

    Set the Startup type to Disabled if it is enabled.

    I started getting this same error message after upgrading to Windows 11 24h2.

    I started a powershell prompt (admin) and used winget to upgrade bonjour service.

    'winget upgrade bonjour'

    It upgraded me from 3.0.0 to 3.1.0.1

    The error seems to have gone away.

    I ended up running this in PowerShell as an administrator.

    winget uninstall bonjour

    then

    winget install apple.bonjour

    There seems to be 2 bonjour packages available. Bonjour Paris! from msstoe and Bonjour(apple.bonjuor). I just picked one.

    Havent had the error in a few days now

    After modifying my registry as you specified above, my PC fails to boot. I needed to restore the system stored 3 days ago to make my PC work again. I do not recommend to do this!

    I have not.

    I did some digging, turns out a 3d cad software I use called solidworks has bonjour as one of its requirements and installs along with the software.

    Is there a way I can actually fix this pop up and fix the error instead of uninstalling the software? Uninstalling is not a choice for me, and I use it daily.

    Thanks
