I truly hate to reprimand in the public forum but in this case it is important for all who visit: This is one of the most irresponsible suggestions & should never be suggested. It is not how to update default settings in the Normal.dotm template nor is it the way to replace Normal.dotm under any circumstances. That template can be effectively created only by the program as explained in my reply o the OP.
Quite frankly, I am requesting that you Delete the reply.
I agree and modified the post to warn that it not be used. I may get into trouble for this and accept that risk.
Only Word can create a fully-functional Normal template.
It should never be overwritten by a different template. The Normal template created by Word can be modified fairly easily. Templates in Microsoft Word.
