How to list installed font families?

In PowerShell you can get the Font families in two lines, one to load the .NET reflection and the second actually gets the font families:

[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
(New-Object System.Drawing.Text.InstalledFontCollection).Families

The outlook looks similar to:

Installed fonts are listed in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts so you can check it with regedit or just run the below command

reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts" /s

Alternatively run this in PowerShell

Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts'

This gives you the real font names along with their corresponding font files, unlike dir C:\windows\fonts\*.* which only lists font file names and you won't know what things like GenBkBasB.ttf or FRABKIT.TTF represents

Sample output:

PS C:\> reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts" /s | select -First 12
