How should I store and manage user settings

I have a windows service whose settings are stored in an ini file in C:\Documents and Settings\All Users\Application Data\company\product and handled by Nini. Now I will write a similar application and look at if I can do a better solution this time. How do you want me to save all program settings. Where should the file be saved? Which tool should I use for handling the file?

The setti开发者_如何转开发ngs should be easily changed by the customer directly in the file. It must be a fix directory.

You can use Isolated Storage. Or see for other alternatives
