Windows 10, Microsoft 365 and Microsoft Store free fonts

Whenever I install a new version of Microsoft Windows, I am always intrigued by what new fonts are included. This started when I was creating websites and didn't want to rely on "Times" or "Helvetica" as the standard fonts available in web browsers like Netscape or IE. So it helped to know what fonts would be available on most Windows PCs.
Currently Windows 10 includes 149 fonts, excluding bitmap ones. This is a far cry from just Arial, Courier, Times New Roman and Symbol that were the TrueType fonts in Windows 3.1. I have shown the Windows XP fonts in bold, which is uselful if you want to ensure that all current Windows users can display the font. Language specific fonts are shown in italics. Here is the current list for Windows 10 20H2:

I have shown the ones that are NOT also found in Office 2007 in bold. There are 219 office fonts:

I have left out some of the system-type fonts that consist of icons and symbols used internally by programs such as Outlook or OneNote. There are also "cloud fonts" which you can download. To get the cloud fonts, your device needs to be online and connected to the Internet. In apps running on Windows (such as Word), go to "File" > "Account", select "Manage Settings" under "Account Privacy", and turn on "Optional connected experiences". Clearing the check box turns off cloud fonts and other online services from Microsoft. This is helpful to de-clutter your font menu.
But wait, there's more! The Microsoft Store offers several additional fonts for free, in addition to some that are sold in the store. The free ones are:

These font listings were compiled with the help of Typograf, a very useful font management program. You can use it to "Unload" fonts as well as Uninstall them. There are a lot of fonts that are clearly intended for specific languages that I have unloaded. Typograf shows the fonts in filename order by default, which explains why some of the font images appear to be in a different order to the font list.
Microsoft has published several explanations about its fonts, as well as a list of fonts for Windows 10. It also has an explanation of each font's background and purpose. Remember if you are using optional or downloaded fonts that if you send a document to someone else, or use the font in an email, the person who receives it won't see the font correctly unless they also have it installed. To avoid this problem, export the document as a PDF or embed the fonts in the document. PDF is better: it preserves all the formatting and spacing correctly, as well as embedding the fonts you used.
Update Monday 1 Feb 2021: I have found this useful article about deleting fonts. As a result, I created the following registry file to remove the "foreign" fonts that I don't use.
