Uninstalling programs like GTA San Andreas can be difficult as uninstallers may leave behind files and registry entries. The standard Windows uninstall option and the game's own uninstaller may not fully remove GTA San Andreas. An uninstall tool is recommended as it can quickly scan for and remove any remaining files or registry values from an uninstall in just a few minutes. It runs the standard uninstall process before scanning the registry and files system to clean up anything left behind from the uninstall.
