@apocalypse any advice on how to apply these registry changes in C# code ? — Ahmed na, Apr 14 '17 at 11:36
Use the `Registry` class. http://stackoverflow.com/questions/8816178/modifying-the-registry-key-value — apocalypse, Apr 14 '17 at 11:51
There's no API for this. The user already has a way to do this. — David Heffernan, Apr 14 '17 at 15:08
Ask yourself, what if two programs did this? What if some other app wanted small icons? — Anders, Apr 15 '17 at 12:45
@Anders The WPF i'm working on does customization to display setting to improve user experience (bigger icons) , but if there is no such api , will have to tell him before using the application . — Ahmed na, Apr 16 '17 at 06:35

Folder icon settings are often per-folder and you will have a hard time forcing your preferences on them. You can probably find some descriptions of the registry locations and format if you search the internet for "shellbags" but this puts you in undocumented territory.

The desktop icon mode can probably be changed by undocumented/hacky means but you should just let the user do it.

You might be able to change the double-click mode by playing with fDoubleClickInWebView and SHGetSetSettings.
