Set wallpaper for your folder

1. Open Command Prompt and set folder attribute to "system". Suppose there is a folder "Setup" in "D:\" drive, in which you want to set a wallpaper as background image. So give following command in Command Prompt:
attrib +s D:\Setup
It'll change the attribute to "system".

2. Now open Notepad and paste following code:
[ExtShellFolderViews]{BE098140-A513-11D0-A3A4-00C04FD706EC} = {BE098140-A513-11D0-A3A4-00C04FD706EC}
[{BE098140-A513-11D0-A3A4-00C04FD706EC}]Attributes=1IconArea_Image=path_of_the_wallpaperIconArea_Text=0x00000000
Now change "path_of_the_wallpaper" to the exact path of the wallpaper which you want to set as background. Suppose the wallpaper is stored in "D:\Wallpaper\Image1.jpg", then the code will be as following:
[ExtShellFolderViews]{BE098140-A513-11D0-A3A4-00C04FD706EC} = {BE098140-A513-11D0-A3A4-00C04FD706EC}
[{BE098140-A513-11D0-A3A4-00C04FD706EC}]Attributes=1IconArea_Image=D:\Wallpaper\Image1.jpgIconArea_Text=0x00000000
NOTE: If you copy the wallpaper in the same folder which you are editing, then you can simply put the wallpaper name in the file. e.g. if you copy the "Image1.jpg" file in "Setup" folder, then the code will be as following:
[ExtShellFolderViews]{BE098140-A513-11D0-A3A4-00C04FD706EC} = {BE098140-A513-11D0-A3A4-00C04FD706EC}
[{BE098140-A513-11D0-A3A4-00C04FD706EC}]Attributes=1IconArea_Image=Image1.jpgIconArea_Text=0x00000000
"IconArea_Text" stands for the text color, you can change it to white, yellow, blue, black or any other color. You just need to know the hexa-decimal number of the color and then replace the code in "IconArea_Text" section. A few most used color codes are as follows:
Black - 0x00000000White - 0x00FFFFFFGreen - 0x0000FF00Blue - 0x00FF0000Purple - 0x00C000C0Red - 0x000000FFYellow - 0x0000FFFFIndigo - 0x00FFFF00

3. Now save the file with name "Desktop.ini" (including quotes) and copy the file in the desired folder which is "Setup" in our example.

4. Thats it. Close the folder and re-open it. Now it should show the wallpaper as background.
