If the white background of windows explorer bores you, you can easily put your unfavorite image in the background. This trick is nice one. See a screenshot of my explorer below.

What you have to do is just this much:
__Open your text editor and type the following:
[{BE098140-A513-11D0-A3A4-00C04FD706EC}]
iconarea_image="exact path of the image"
iconarea_text=0x00000000
*type the exact path to the image e.g. E:\wallpapers\frog\123.jpg
do not forget to put the extension of the image like .jpg, .gif etc
__save the file as desktop.ini in the folder whose background you want to change. Close it. Now change the attributes of the file to hidden( right click on the file ---> choose properties ---> check the option hidden)
__open command prompt. Run the following command:
Attrib +s "path of the folder where you have saved desktop.ini"
__ open the folder and see.
*You may copy the same desktop.ini to others folders and change their backgrounds.
*You can change the icon font color.
e.g. iconarea_text=0x00000000 gives black font color and iconarea_text=0x00ffffff gives white color.
