PowerShell: Install Fonts

Font installation using PowerShell has changed since Windows 10 1909. The old way of doing it with PowerShell no longer works. This new script was originally written by Ben Reader who is a fellow Microsoft MVP from Australia. I took the script and modified it by improving on user interface and file tweaks. 

This script gets a list of all font files that exist in the same directory. It then parses through each font file getting the font name attribute at which point it copies the file to c:\windows\Fonts. Next, it registers the font by writing the font file name to HKLM:\Software\Microsoft\Windows NT\CurrentVersion\Fonts so that it will show up in a drop-down menu. The script also writes the status of each step to the screen so the person executing it knows if each font install is successful or not. 

You can download the script from my GitHub site.

      .DESCRIPTION  
           This function will attempt to install the font by copying it to the c:\windows\fonts directory and then registering it in the registry. This also outputs the status of each step for easy tracking.
