What useful functionality is in the newer Microsoft Office that isn't already in the older MSOffice 2007 Pro which I just installed?

Update:

Always striving to add on-topic technical value, here's yet another way to
instantly and easily freely _extend_ the basic functionality of an older MS
Office version so that it can read the newer MS Office formats.

Caveats:
o I tested this only on one machine, and only on MS Office 2007.
o I don't yet have an office document with newer formats to test against.

o This link to the MS Office Compatibility Tool is apparently defunct:
https://www.microsoft.com/en-us/download/details.aspx?id=33298

o This link, supposedly, contains a second source:
http://www.softpedia.com/get/Office-tools/Other-Office-Tools/Microsoft-Office-Compatibility-Pack-2007-File-Formats.shtml

o That results in:
https://softpedia-secure-download.com/dl/ff9aa8f36ae42d6ec36cee005ace7589/5f68a59a/100058971/software/office/FileFormatConverters.exe

o With MS Office 2007 installed, running that resulted in the message:
"Compatibility Pack has been installed."
"Compatibility Pack for the 2007 Office system."
"The installation is complete".

Note: That doesn't show up in:
Win+I Apps Apps & features (it doesn't show up here, unfortunately).

Note: I need to find an incompatible MS Office document to test it with.

In addition, I don't remember if we discussed how to add Save-as-PDF to
easily & freely extend the capabilities of the older Microsoft Office.

Microsoft Office 2007 can only "print" to PDF and not "Save as PDF"
unless you run the "SaveAsPDFandXPS.exe" tool from Microsoft.
o 2007 Microsoft Office Add-in: Microsoft Save as PDF or XPS
https://www.microsoft.com/en-us/download/details.aspx?id=7

Run the SaveAsPDFandXPS.exe _after_ installing Office 2007.

You should see it show up in your installed programs listing:
o Win+I Apps Apps & features
Microsoft Save as PDF or XPS Add-in for 2007
Microsoft Office Programs version 12.0.4518.1014 (same as office version)

If you have a link to an incompatible newer format to test, let me know.

It seems to me that a current Libre Office would be a better choice.
