I keep all my utilities in a desktop folder. When I choose the "Hammer Screw Driver" icon through Properties>Customize>Change Icon it changes the folder icon to the Control Panel icon. I've tried a dozen other ones as a test and every one works! What has happened to that icon and how can I repair it? Thank You!
You could try refreshing the icon cache.
Right-click on the desktop, choose Properties, click on the Appearance tab in the dialog box that pops up, and click on the Advanced button on that tab.
Select Icon in the Item list and increase the Size setting by 1 pixel (this will normally be from 32 to 33). Click on OK to dismiss the Advanced Appearance dialog, then click on the Apply button.
The desktop will fade and then return back to normal. Now click on the Advanced button again, change the icon size back to what it was, click on OK, and click on OK again.
If no joy may be some help at the link below.
