My Dell desktop came bundled with Atheros Bluetooth Suite 64. I presently have no use for this program. If I install it, and later change my mind, will I be able to reinstall it?
If it's a built-in component, then yes you can install it later from the CD that arrived with your computer or from Dell Support. Keep in mind that if you need Bluetooth support, you will have to actually keep the driver and software installed.
