Not sure if anyone's posted the underlying cause for this change in font installation behaviour, but I had to fix this in my environment and here's what I found:

As of build 1809 (I think?) Microsoft changed the way fonts install in the OS - in order to allow non-admin-privilege users to install fonts, the default behaviour is to install a new font under the user profile and -- importantly -- add it to a new section of the registry. My suspicion is that most the application problems being posted on here is due the apps referencing the original 'all users' reg location for fonts. As previously posted, running the 'Install for all users' option fixes it, but that doesn't help if you're looking for a scripted solution.

Long story short, I wrote a PowerShell script to install the fonts for all users for our OS Deployment Task Sequences in SCCM. It copies the fonts to the main C:\Windows\Fonts directory and creates the required registry entries to make the fonts appear for all users:

<#

.SYNOPSIS

    Installs fonts used for [Company Name] brand.

.DESCRIPTION

    Installs [Company Name] fonts using new method/syntax required for Windows 10 1809 or greater.

    Error Log: C:\Temp\Install-CompanyFonts.log

.NOTES

    Create a folder named Fonts in the same location as the script, and copied desired Open-Type or True-Type font files into this folder.

    Revision:

#>

$logfile = "C:\Temp\Install-CompanyFonts.log"

Function Write-ToLog {

    Param (

        # Message text to be added to log file

        [Parameter(Mandatory=$true)]

        [string]

        $Message

    )

    # Set timestamp

    $timestamp = Get-Date -Format u

    # Write log file entry

    "$($timestamp)  :  $Message" | Out-File $logfile -Append

}

#Timestamp log file entry

#Write-Host "Time-stamping log file entry..." -ForegroundColor Yellow

Write-ToLog "START"

Set source files and destination

$source = "$PSScriptRoot\Fonts"

#Write-ToLog "Fonts to install: $($source | measure | select -ExpandProperty Count)"

Set COM Shell object for obtaining file list and details

$objShell = New-Object -ComObject Shell.Application

$objFolder = $objShell.namespace($source)

Copy each font to system font directory and create matching registry value

foreach ($font in $objFolder.items()) {

    # Generate values needed for reg key

    $fontName = $($objFolder.getDetailsOf($font, 21))

    $fileType = $($objFolder.getDetailsOf($font, 2))

    $fontType = "(",$fileType.replace(' font file',''),")" -join ""

    $regKeyName = $fontName,$fontType -join ' '

    # Check that font isn't already installed and is a TrueType / OpenType font

    if (!(Test-Path "C:\Windows\Fonts$($font.Name)") -AND (($fileType -eq 'OpenType font file') -OR ($fileType -eq 'TrueType font file'))) {

        Try {

            Copy-Item -Path $font.Path -Destination "$env:windir\Fonts"

            New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts" -Name $regKeyName -Value "$($font.Name).otf" -PropertyType String -Force

            Write-ToLog "Installed font $($font.Name)"

        } Catch {

            Write-ToLog "Failed to install font $($font.Name)"

        }

    } Else {

        Write-ToLog "Failed to install font: $($font.Name)  |  File already exists or font is not OpenType/TrueType"

    }

}

Write-ToLog "FINISH"

We had the same problem, it was driving us crazy!   Everytime we "reinstalled" our fonts, when we did a re-start on the computer they were gone.   Finally fixed!  Fonts need to be installed with "install for all users".  Drag and drop does not work.

Hope that helps

I'm having the same problem with viewing the fonts in my system. However, to get mine to work with my programs (photoshop etc), when I download a font I make sure it's not in a zip folder, then right click on the font and select install for all users.

THIS WORKED!!!!....finally.  Thanks xtreamdev.  Such a simple solution when you know

Can you hold for a while so i can search other solution for you.

Thanks
