My dad has Win 7 Home Premium x64, he used 7tsp and changed to the Predator theme from here, then he went back to normal & ever since the Start Orb has stayed at the Predator theme custom orb. I just want to know how can I restore it back to the default Windows 7 Start Orb w/out a back-up considering he did not do any back-ups & he did not use 7tsp to restore it, he just changed to one of the default Win 7 themes that come w/ the OS & the Predator theme Start Orb has stayed ever since.
