Close Word

Locate the normal template. If you have not changed the default location enter or copy
%appdata%\Microsoft\Templates
to the address window of Windows File Explorer and you will be taken to the folder that contains the default template. Note that this folder is normally hidden.

Set the File Explorer to display hidden items.

See if there are any lock files present - in particular a file named '~$Normal.dotm'. Delete any files that begin with '~$'

Rename the Normal template to (say) oldnormal.dotm.

Restart Word.

Is the macro still present? If it is, it is not stored in the default template, but in another template of the same name, which is almost certainly located in the Word startup folder - If you have not changed the preferred startup folder it can be located (in English language versions of Windows) by typing
%appdata%\Microsoft\Word\Startup
in the Windows File Explorer Address bar and pressing Enter.

If this is the case, close Word again and rename the template in the startup folder to (say) MyMacros.dotm and you can restore your original default template by renaming it back to normal.dotm.
