Eject Your CD or DVD ROM AND Insert The CD or DVD ROM

Insert option CD or DVD drive…

As default, you can only EJECT the optical drive from the drive icon in My Computer to insert CD/DVD. To Load/INSERT the CD/DVD, You must press the LOAD/INSERT BUTTON of the optical drive.
This would cost you some energy to make your hands and bend or whatever to reach the button.
Instead of that, you can install the small setup in registry which will add "INSERT" to the right click menu of your optical drive.
Therefore, You can EJECT/INSERT with just clicks. No need to reach the button of your optical drive.
