Here's the key you want:
这是你想要的钥匙：
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\http\shell\open\command
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\http\shell\open\command
And here's a quick registry tutorial for C#, if you need it.
Edit:
编辑：
For per-user settings, use this key:
对于每用户设置，请使用此键：
HKEY_CLASSES_ROOT\http\shell\open\command
HKEY_CLASSES_ROOT\http\shell\open\command
(HKCR has both machine and user settings, user takes priority).
（HKCR 有机器设置和用户设置，用户优先）。
Note that this might not work on Vista. For more info, see here.
请注意，这可能不适用于 Vista。有关更多信息，请参见此处。

Based on your answers I wrote this sample code that should do what you want (not tested)
根据您的回答，我编写了此示例代码，它应该可以满足您的要求（未测试）
public static string GetDefaultBrowserPath()
{
string defaultBrowserPath = null;
RegistryKey regkey;
// Check if we are on Vista or Higher
OperatingSystem OS = Environment.OSVersion;
if ((OS.Platform == PlatformID.Win32NT) && (OS.Version.Major >= 6))
{
regkey = Registry.CurrentUser.OpenSubKey("SOFTWARE\Microsoft\Windows\shell\Associations\UrlAssociations\http\UserChoice", false);
if (regkey != null)
{
defaultBrowserPath = regkey.GetValue("Progid").ToString();
}
else
{
regkey = Registry.LocalMachine.OpenSubKey("SOFTWARE\Classes\IE.HTTP\shell\open\command", false);
defaultBrowserPath = regkey.GetValue("").ToString();
}
}
else
{
regkey = Registry.ClassesRoot.OpenSubKey("http\shell\open\command", false);
defaultBrowserPath = regkey.GetValue("").ToString();
}
return defaultBrowserPath;
}

I just made a function for this:
我刚刚为此做了一个函数：
public void launchBrowser(string url)
{
string browserName = "iexplore.exe";
using (RegistryKey userChoiceKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice"))
{
if (userChoiceKey != null)
{
object progIdValue = userChoiceKey.GetValue("Progid");
if (progIdValue != null)
{
if(progIdValue.ToString().ToLower().Contains("chrome"))
browserName = "chrome.exe";
else if(progIdValue.ToString().ToLower().Contains("firefox"))
browserName = "firefox.exe";
else if (progIdValue.ToString().ToLower().Contains("safari"))
browserName = "safari.exe";
else if (progIdValue.ToString().ToLower().Contains("opera"))
browserName = "opera.exe";
}
}
}
Process.Start(new ProcessStartInfo(browserName, url));
}
