How to delete settings for a .Net application

Some .Net applications (built with Visual Studio 2005 or later) utilize the My.Settings object for storing user application settings.  Sometimes if an application fails to load after you've previously witnessed it load successfully, it is possible that one of the settings is to blame.   Windows controls the storage location for these settings and it varies between different versions of Windows.

For Windows Vista, 7, 8, 10, 11 or later:
"C:\Users\YourUserName\AppData\Local\Manufacturer"

For Windows XP or Windows 2000:
"C:\Documents and Settings\YourUserName\Local Settings\Application Data\Manufacturer"

Make sure the app is not running.  Once you navigate to the settings storage folder, you may see multiple folders within it all starting with the application name, or possibly other application names from the same manufacturer as well.  Delete all of the folders that start with the name of the application your trying to reset (DO NOT delete any files).  After deleting the folders, restart the application and it will start with the default settings set for the app.
