Uninstallation is the process of removing software or applications from a computer or device. This can be done through the operating system's settings or control panel, where users can find a list of installed programs. By selecting the desired software and choosing the uninstall option, the program is deleted from the system, freeing up storage space. During uninstallation, the system typically removes all associated files and settings related to the software. However, some residual files may remain, which can be cleaned up using additional tools. Proper uninstallation helps maintain system performance and prevents potential conflicts with other software.
