Here's how to show icons, hide them, or change their size in Windows.
To show or hide desktop icons
Hiding all the icons on your desktop doesn't delete them, it just hides them until you choose to show them again.
To resize desktop icons
You can also use the scroll wheel on your mouse to resize desktop icons. On the desktop, press and hold Ctrl while you scroll the wheel to make icons larger or smaller.
