How can I configure the default Internet Browser?

How can I configure the default Internet Browser?: "Start the registry editor (regedit.exe)
Move to HKEY_CLASSES_ROOT\http
Expand the tree and move to HKEY_CLASSES_ROOT\http\shell\open\command, double click on default and set the string to the command you wish to run for Internet addresses, for example
'E:\Program Files\Internet Explorer\iexplore.exe' -nohome for Internet Explorer
E:\Program Files\Netscape\Communicator\Program\netscape.exe -h '%1' for Netscape
Click OK
Move to HKEY_CLASSES_ROOT\http\shell\open\ddeexec\Application, and again double click Default, change to the browser, NSShell for Netscape, IExplore for Internet Explorer.
You may also want to change the icon associated, move to HKEY_CLASSES_ROOT\http\DefaultIcon, (do I need to say) double click Default and set to the icon
%SystemRoot%\system32\url.dll,0 Internet Explorer
E:\Program Files\Netscape\Communicator\Program\netscape.exe,0 Netscape Navigator
You should repeat the above for https as well, i.e. HKEY_CLASSES_ROOT\https\shell\open\command etc. "
