Resize desktop icons

Not happy with the size of the icons on the desktop or in Windows Explorer? It's a snap to change their size in Vista. Press the Ctrl key and scroll your mouse wheel (or trackpad equivalent) forward to enlarge the icons, or toward you to shrink them. You'll have many degrees of size to choose from, and they'll stay at the new size until you change them again.
If you don't have a wheel on your mouse or trackpad, there are still several ways you can change the size of the icons. For a quick way, but with few choices for icon sizes, right-click the desktop and select View. You can now choose small, medium or large icons.
If you want more choices, right-click the desktop and choose Personalization. Click Open classic appearance properties for more color options, click the Advanced button, choose Icon from the drop-down list, and use the Size control to change the size. Click OK, then keep clicking OK until all menus disappear.
In Windows XP, right-click the desktop and choose Properties. Click the Appearance tab, then the Advanced button. Choose Icon from the drop-down list, and use the Size control to change the size of the icons. Click OK, then keep clicking OK until all menus disappear.
