Existe alguma maneira de verificar qual navegador é primário em uma máquina específica em um Windows 10? Como posso encontrar essa informação programaticamente? Powershell talvez? Ou Python? Obrigado por qualquer sugestão.

reg query "HKCU\Software\Microsoft\Windows\Shell\Associations\UrlAssociations" -v Progid -s

do prompt de comando do Windows deve retornar (valores legíveis, por exemplo, FirefoxURL , ChromeHTML , IE.HTTP ) Progid para a maioria dos protocolos (principalmente ftp , http , https etc.), e. da seguinte forma: 

==> reg query "HKCU\Software\Microsoft\Windows\Shell\Associations\UrlAssociations" -v Progid -s

HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\ftp\UserChoice
    ProgId    REG_SZ    ChromeHTML

HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice
    ProgId    REG_SZ    ChromeHTML

HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\https\UserChoice
    ProgId    REG_SZ    ChromeHTML

HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\irc\UserChoice
    ProgId    REG_SZ    ChromeHTML

HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\mailto\UserChoice
    ProgId    REG_SZ    ChromeHTML

Existe alguma maneira de verificar qual navegador é primário em uma máquina específica

O navegador principal pode ser diferente dependendo do protocolo ao qual você está se referindo.

Você pode usar ftype em um shell cmd para verificar os diferentes protocolos.

Exemplos: 

> ftype | findstr http
http="C:\apps\Firefox\firefox.exe" -osint -url "%1"
https="C:\apps\Firefox\firefox.exe" -osint -url "%1"

> ftype | findstr ftp
ftp="C:\apps\Firefox\firefox.exe" -osint -url "%1"

etc ...
