Welcome to part 3 of Customize Your PC. In this post, I will briefly show you how to make your own icons for use in Windows.
The first thing you will need to do is get, and install, a free open source image editing program called GIMP (GNU Image Manipulation Program).
Next, gather images that you would like to make into icons. The thing to remember when doing this is that they are going to be resized to 255×255 or smaller, so it works best if they are already square. Also, it’s best to use images that are already roughly that size and that are not too complex. When you resize and save as an ico file, they tend to lose a little quailty and sometimes things get blurred.
Step 1: Open GIMP. The only window that opens is a small narrow window with all of GIMPs controls.

Step 2: Open the image you want to make an icon by going to File > Open. GIMP will load the image in a new window.
Step 3: First thing you need to do is resize the image (if you are using an image that is at or below 255×255 in size, skip this step). In the new window, go to Image > Scale Image:

A new window will open:

The portion with the black square around it is all you need to worry about. Type in 255 or a value less than that in whichever box has the highest value. GIMP will automatically change the other to keep the ratio true. The end result is that both width and height values must be 255 pixels or under. Click the Scale button to apply changes and close the window.
Step 4: Now you need to re-save the image as a Microsoft Windows Icon image.
- In the image window, click File > Save As. Since this is most likely your first time using GIMP, you will need to expand “Browse for other folders” and futher down “Select File Type” to see the options you need. First, browse to where you want to save the new image. Then, down under the newly expanded “Select File Type” you will need to scroll down and select Microsoft Windows icon. This will add the extension .ico to the end of your new file. Name it as you wish then select Save.
- When you do this, it will pop up a window with a preview of the image and a drop down menu with something like ‘32bpp, 8-bit alpha, no palette’. Just ignore all this and click Save again. If it pops up another window telling you you need to export, just click Ignore.

Now, it is time to put your new ico file into use. If you wish to replace a system icon such as the “My Computer” or the recycle bin, follow step 5A. If you wish to replace the icons used in Windows Explorer for your hard drive(s), follow step 5B. If you wish to replace a desktop shortcut icon, follow step 5C.
Step 5A: Right click on your desktop and select Properties. The Display Properties window will open; now select the Desktop tab. At the bottom of the window, click on the Customize Desktop button.

Select an icon you wish to change, click Change Icon, navigate to where you saved your ico file and select it. All done!
Step 5B: Replacing the hard drive icons is not as simple. First thing you need to do is copy the icon to the root of the hard drive and rename it HDD.ico. Now, you will need to open Notepad (Start>Programs>Accessories). Type in the following exactly as you see below:
[autorun]
icon=HDD.ico
Click file, save. In the save window, set the “Save as type” option to “All Files” then save the file as autorun.inf and save it to the root of the hard drive (same place as the icon).
Now you will need to reboot the computer before it uses the new icon.
Step 5C: Right click on the shortcut, click Properties. Click “Change Icon” and the rest is the same as step 5A.
That’s it. If I left something out or you are confused, leave a comment or send me a message.
