Various embodiments for improving application uninstallation from a computing device are described. In one or more embodiments, a scanning application may generate a files list that includes information about what other applications may use ancillary files. When an application is deleted, a user interface presents a list of ancillary files used by the deleted application and what other applications may use the ancillary files. The user may then select which ancillary files to delete along with the application. Other embodiments are described and claimed.
