There really isn't any thing to it. All you have to do is single-click on one of your icons. Then simply hold down the CTRL button and scroll the wheel on your mouse (or drag your finger if you have a laptop and use the pad) at the same time. The icons should change size. You can make them either bigger or smaller. Like I said earlier, I did this in Windows Vista Business. If it doesn't work in the other versions (Basic, Home Premium. ect.) or if it does works in Windows XP please comment! Thanks!! Have Fun!!
Note:This changes all of the icons. Some icons change more than others.
P.S. Comment me with ideas for uses using this feature.
