In the IconPane you will see the content of the file containing the icon used for the current object. You can assign or reset icons for multiple objects at once and to set or reset an icon for a file type, you can launch Icon Changer for any file of the desired type. If Icon Changer can change its icon, you will see the Change Icon symbol but bear in mind that not all icons can be changed.
To use it, select the file you wish to personalize and right click it with your mouse. You can use IconChanger to change personal file icons by assigning an icon of your choice to each and every file on your computer. One great way to personalise your desktop is to customise your icons. Icons are one of the main ways we identify programs and documents but they can often be bland and boring especially those default ones assigned by Windows.
