Installing and uninstalling a lot of software can use up your Dell Inspiron 1721's resources, and may infect your computer with viruses, corrupting your system. A factory restore may be the quickest way to clean things up. This type of restore is also useful when you sell or give away the computer and need to delete personal data and software. Regardless of the reason, performing a factory reset on a Dell Inspiron 1721 is fairly easy.
