In 2010, Blizzard Entertainment published the long-awaited real-time strategy sequel "StarCraft II" for the computer. Like many other games, installation involves writing data to the hard drive. But "StarCraft II" will also not always uninstall everything from a computer when it is removed. Some files may remain on your computer, and your registry may also contain some traces of the installation. To get rid of any trace of "StarCraft II," you must manually remove parts of the game.

Open your Control Panel and select "Uninstall a Program." Click "StarCraft II" and select "Uninstall." Wait for the program to uninstall.

Open the folder where "StarCraft II" was installed. You chose the location during installation and the location can vary among different operating systems. Click the "StarCraft II" folder. Simultaneously press "Shift" and "Del" to permanently delete the folder.

Press the "Start" key and type "regedit." Press "Enter." Click any entry with "StarCraft" in it and press the "Del" key to delete.

Reboot your computer to finalize changes.
