the problem here that its not even saving in my systemQuote:
I assume you use WPF as your UI project.
Those property settings are saved on the user profile of your operating system. So you can save and load them easily with the code you provided. But they can't be saved at the same folder as the executable is.
You can write your own simple persistence system by havin a class which acts as a model (e.g. AccountSettings), which contains all the information that needs to be saved and a persistence class which saves and loads the data.
For saving: Serialize this data as json or xml and write the serialized data into a file which points to the application folder.
For lading: Unserialize the data from the file and put it back into the model class
