Uninstalling or Changing a Program
If an application is not uninstalled properly, you might be leaving files on the hard drive and unnecessary settings in the registry, which depletes the hard drive space and system resources. Unnecessary files might also reduce the speed at which the registry is read. Microsoft recommends that you always use the Programs and Features utility, as shown in the figure, when removing, changing, or repairing applications. The utility guides you through the software removal process and removes every file that was installed. In some instances, you can install or uninstall optional features of an application using the Programs and Features utility. Not all programs offer this option. To open the Programs and Features utility in Windows 7 and Windows Vista, use the following path: Start > Control Panel > Programs and Features In Windows XP, use the following path: Start > Control Panel > Add or Remove Programs
