Windows: If you've put off tweaking the size of your desktop icons because you assumed it would be a pain, it's time to enjoy some hassle-free resizing without digging in menus or replacing icon packs.

You can resize the icons using a simple keyboard and mouse combination. Lifehacker reader Guard stumbled across the shortcut by complete accident and was quite pleased with the discovery.
You can increase and decrease the size of your desktop icons in Windows 7 using CTRL + Mouse Scroll. It's a great trick for both those who like to tightly fit a lot of icons, and those who have very few icons and want a larger view instead.
I've been using Windows 7 since the beta, and I've never seen this mentioned. I accidentally discovered it when intending to zoom in Chrome.
All you have to do is click on your desktop to make sure it's in focus, then hold down control and scroll up or down to resize. In the image above the middle icon was the default size, the left icon was a small as we could go, and the right icon was as large as we could go — at the largest the icons were 256x256 pixels. Thanks Guard!
