On Windows 10 I have accidentally set the association for .dll files to Notepad++ - how can I remove the association so that dll files go back to having no assocation?

I found this question, which concerns .exe files rather than .dll

I have poked aorund the registry, but I can't seem to find any Notepad++ entries for associations

Use this REG file to reset the association settings for .DLL file type.

Windows Registry Editor Version 5.00

[-HKEY_CLASSES_ROOT\.dll]

[HKEY_CLASSES_ROOT\.dll]
@="dllfile"
"Content Type"="application/x-msdownload"

[HKEY_CLASSES_ROOT\.dll\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"    

[-HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.dll\UserChoice]

Copy the above lines to Notepad and save the file with .REG extension. Double-click the file to apply the settings to the registry.
