You may be the only person on Windows who has only one browser installed.

That's not as easy as you seem to think it is.
Each program you install can add its own fonts.

That comment indicates you don't understand how font fingerprinting works.
They tabulate ALL the fonts on your computer. Not just what you use.

Run this program please. <https://amiunique.org/fp> and save the results
to text, and paste your results into the reply like I did and we can solve
the fingerprinting issues together using real world data of our own.

The way you normally approach fingerprinting usually is you start with the
worst entropy and when you fix that, you move down to the next worst
entropy, and so on, until you're no longer unique or nearly unique.

In the best case, you want to blend in with the crowd.
Here are my current AmIUnique.txt values using one Firefox browser.

As expected, many things are worse than fonts in terms of entropy.
But fonts aren't good either.

All I want is an easy way to randomize the contents of a Windows folder
using the native tools that come with every Windows 10/11 installation.
