Remove means you must uninstall thats way it will remove its registries also.\n\n3rd. You can remove registries from \nControl Panel -> Add&remove programs (select properly the programs/games which is not necessary and you are not using or you may have lots of demo versions that is occupying space.\n\n4th run the disk defrag from system tools\n\nafter all these process.\n\nShutdown the computer completely and turn it on.
