Batch - Default Browser?

Question

Is there a way for using a batch file to find the default browser on my computer?

Answer 1

Thank you, @Rob.

@Rob's answer is close, but it still only pulls the ProgId. This one will set the browser name as reported by the ProgId (not always what you expect) in the browser variable, the specific verb used as browserverb, and the cmd path as browsercmd:

setlocal enableDelayedExpansion
:: parse the ProgId
FOR /F "usebackq tokens=1,2,* delims==" %%A IN (`REG QUERY "HKCU\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice" /v ProgId 2^>NUL ^| more +2`) DO (
    SET browserstub=%%C
    :: parse for Class information
    FOR /F "usebackq tokens=1,2,* delims==" %%R IN (`REG QUERY "HKCR\!browserstub!" /v AppUserModelId 2^>NUL`) DO SET "browser=%%T"
    FOR /F "usebackq tokens=1,2,* delims==" %%R IN (`REG QUERY "HKCR\!browserstub!\shell" /ve 2^>NUL`) DO SET "browserverb=%%T"
    FOR /F "usebackq tokens=1,2,* delims==" %%R IN (`REG QUERY "HKCR\!browserstub!\shell\!browserverb!\command" /ve 2^>NUL`) DO SET "browsercmd=%%T"
)
:: display results
SET browser
