You probably remember something like this choice popping up when you installed Visual Studio:
But, if you happen to forget what choice you made, you can quickly get a reminder by going to HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\<version>\Profile. So, for Visual Studio 2010 the path would be HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\Profile and then you would look at the "LastResetSettingsFile" string:
Assuming you haven't reset the settings via Tools -> Import and Export Settings lately this value will have the name of the settings file you chose during the install. In my case, I chose the "General Development Settings" option during my install.
