No need to actually delete or remove any reference for basic MS kybd., that's native to the OS. Just install your new s/w and it should or better direct how its to be installed. You can then check at the control panel at kybd. icon what's present after the install, some reference to your new status will be listed and selected. If not selected, then select it from the list, there.

I would think the manual or some help guide was present with your h/w. Check to see if a .PDF o >DOC file to be displayed will better explain its install process.
