How can I find of all the browsers and their details that are installed on a machine.

What angle are you coming from, a windows forms app? – Nick Craver Mar 03 '10 at 11:27

I am looking after making a library that can do this, a console application would do – Pranali Desai Mar 03 '10 at 11:29

Looks like you've got a good answer below on windows platforms. On the Non-windows side, I'd build out a hearty least-common-denominator bourne shell script which would check OS type / distribution, check the associated package managers, check the file systems for binaries, etc. Would be nice to just have it wget your script off of a remote site, but your'e not guaranteed wget on a lot of Unix platforms. – Wedge Martin Sep 11 '15 at 16:17

A quick google search gave me Finding All Installed Browsers in Windows XP and Vista
In the application I’ve been working on, I needed to find all browsers that are installed on a user’s machine. The best way to go about this is to look in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet. This is where browser manufacturers are told to put their information, per this MSDN article.

3... But here’s a gotcha I hit: on 64bit, the keys get written to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Clients\StartMenuInternet. – SepehrM Apr 28 '14 at 18:32

Except for Microsoft Edge. Since it is the default browser in Windows 10, this has caused me some issues since the registry key stated above has the current default set to iexplor.exe (IE 11), which it is not – BeanFlicker May 11 '16 at 00:37
A short answer:
using (RegistryKey hklm = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32))
{
RegistryKey webClientsRootKey = hklm.OpenSubKey(@"SOFTWARE\Clients\StartMenuInternet");
if (webClientsRootKey != null)
foreach (var subKeyName in webClientsRootKey.GetSubKeyNames())
if (webClientsRootKey.OpenSubKey(subKeyName) != null)
if (webClientsRootKey.OpenSubKey(subKeyName).OpenSubKey("shell") != null)
if (webClientsRootKey.OpenSubKey(subKeyName).OpenSubKey("shell").OpenSubKey("open") != null)
if (webClientsRootKey.OpenSubKey(subKeyName).OpenSubKey("shell").OpenSubKey("open").OpenSubKey("command") != null)
{
string commandLineUri = (string)webClientsRootKey.OpenSubKey(subKeyName).OpenSubKey("shell").OpenSubKey("open").OpenSubKey("command").GetValue(null);
//your turn
}
}

For any beginners like me. To run this I had to create a new wpf project in visual studio and follow https://stackoverflow.com/a/62390032/8608146 then run. – Phani Rithvij Jun 12 '21 at 06:15
Scan the contents of the Program Files folder for the filenames of known browser executables.

2+1 because it is an option, and remember to also scan 64bit program files. – JL. Mar 03 '10 at 11:42
Necromancing, as the provided answers are incomplete.
First:
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet.
won't get you all browsers.
If you're in a corporate environment, the user will not have admin rights. If Google-Chrome and/or Chromium are installed that way (don't know if FF works like that), then the key will only be in HK_Current_User.
Also, this doesn't cover non-windows operating systems. You'll need elaborate code to determine and cover all package-management system on Linux + Mac systems.

Hi stefan, can you please add lines of code to get default browser? Thanks – Mrityunjay Dec 02 '16 at 11:03

The default-browser is simple: Just open the URL as process - on Linux, this will require gvfs to be installed - which it usually will be - on desktop-linux. – Stefan Steiger Jan 02 '18 at 16:35
This solution seems to work for me:
RegistryKey browserKeys;
//on 64bit the browsers are in a different location
browserKeys = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\WOW6432Node\Clients\StartMenuInternet");
if (browserKeys == null)
browserKeys = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Clients\StartMenuInternet");
string[] browserNames = browserKeys.GetSubKeyNames();
Enjoy coding! Chagbert.
