Batch - Default Browser?

Question

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

Answer 1

This code will set the Environment variable browser to FirefoxURL which gives you a good indicator:

@ECHO OFF
REG QUERY HKCU\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice > browser.txt
FOR /F "skip=2 tokens=*" %%G IN (browser.txt) DO ( SET browser=%%G )
SET browser=%browser:~20%
ECHO Is: %browser%

It works by querying the registry to a text file then skipping the first two lines (useless for your purposes), then taking the text that starts at the 20th character of te remaining line. Which gives you FirefoxURL
