Shollybee is only right about your first question. Embedded fonts should display correctly in all versions of Word that support the feature, whether the fonts are installed or not.
The Word interface doesn't include a way to get a list of fonts used. It's possible to do with a VBA macro, here's a page with a listing that will list all fonts used, then which ones are not installed: Check Fonts Used in a File
If VBA is too complicated, make a copy of your file in a separate subfolder, then edit the name to add .zip to the end. Unzip the file, then look in the word folder for fontTable.xml. This will list all fonts used in XML that looks like this: <w:font w:name="Symbol"> Then you can check which fonts names are not shown in your C:\Windows\Fonts folder. Tip: drag fontTable.xml to a browser window to make it human-readable.
