Change the background of window

Hi friends,
You can change the background inside a folder...

1. open notepad
2. copy this these texts and paste it in a note pad document and save as "desktop.ini"

[{BE098140-A513-11D0-A3A4-00C04FD706EC}]

iconarea_image=\2.jpg

iconarea_text=0x00ffff

1. The iconArea_Image given in red is the path(absolute path or relative path) of the background picture you want to set (2.jpg)
2. now copy this desktop.ini and the image in any folder and set your favourite pictures as your background images...

(Note:- Sometimes it doesn't work... Please excuse... If any one find out the reason, please tell me...)
