On-Screen Multimedia Keyboard

I did a hardware update about a week ago and downloaded the multimedia
keyboard not realising what it was. I tried to uninstall it once I realised
what it was, but when I restart the computer the system now reports at least
3 new devices, an HID-compliant Device x3, a ToasterDevice00, and a USB Human
Interface Device, and tries to install these devices once the computer starts
up after every time I try to remove the program using Add/Remove Programs. It
is very annoying since I didn't install any of these and don't see why they
should have even appeared with a software program. I'm looking to remove the
program completely because it is not needed.
