How to store changes made in a GUI ?

Question

Hi all,

I have developed a Windows form with 7 tabs. Each tab has some check boxes, radio buttons and labels.
Now when I make changes and close the application, when I reopen it again I want the application to remember the changes that have been done prior on it i.e what check boxes, radio buttons have been checked.
What is the best way to do this? I was planning to write a Xml file and then make changes to that. Is there any other way or better way to do this ?
If there is some sample code that would be appreciated.
