Remove backed up service pack files??

[rgodart 0]

I installed sp2 a while ago with the option to back up the replaced files. Now i would like to remove those files as they're taking space for nothing. Where are they located? And how do i remove the uninstall SP2 option in control panel??

 

Thanks
