Setting in HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\word\options the key DefaultFormat to DocX should resolve this issue.

If the above key does not exist, try the following
Start Word

File -> Word Options -> Save -> Save files in this format

then select Word Doceumnt (*.docx)

This could be caused by an add-in.

Check if you have add-ins and disable/remove them one at a time or all and then add them back one at a time.

Another cause could be:

Run Regedit and navigate to the key: with DATA selected, press
delete. Word will recreate a new key when it is restarted.

I disabled the add-in PDFMaker and the crashes stopped occurring with such frequency.  I think this may have been it.
