I have been making a wallpaper changer, and have made it to a large extent.
Now I want to add some customizable options in the program, Like the search
path for image files for the wallpaper, and whether the program should change
the wallpaper at logon.

1.  Do you think that saving this information in the Windows registry will
be a good idea?
2.  What are the api to access and change keys in the registry? A link to an
MSDN page would be helpful.

Thanks,
