Docx is the file format of Word 2007. Most of the files we use now are Word 2003. We don't want to change word2003 for a few files. What should we do?
The problem is easily solved. This is a problem that word 2003 is compatible with Word 2007. Download and install the patch package for converting Word 2007 to Word 2003.
Now there is a conversion tool provided by Microsoft that is very good (Microsoft Office Word, Excel and PowerPoint File Format compatibility packages), we do not have to install 2007 to open docx files, as shown below:

After the installation, restart the machine and the problem is basically solved. Now we can identify the Word 2007 documents in docx and docm formats, powerPoint 2007 documents in pptx, pptm, potx, potm, ppsx, and psms formats, Excel 2007 documents in xlsb, XLSX, xlsm, xltx, and xltm formats, etc.
