A family of Microsoft word processing software products for creating web, email, and print documents.
Word 2007 (and 2010) does not make or use a Normal.dotx file. It uses only Normal.dotm.
The reason is that *.dotm templates are capable of containing macros (whether or not they actually contain any macros). If you record or write a macro in a .dotx template and then try to save it, Word will warn you that the macros can't be saved and do you want to discard them or back off and save as a *.dotm instead? This is just as true for the Normal template as for any other template. To avoid frustration, MS decided to just make Normal.dotm and not Normal.dotx.
If you deliberately save a template with the name Normal.dotx, you can use it like any other template -- but it still won't be "the" Normal.dotm template.I can definitely see it in the Open dialog. Apparently, though, MS considered it too confusing to show a template named Normal in the General tab of the New Document dialog.
