To resolve such problems, you must use the uninstall function of Windows for the program to be removed safely.Clean out temporary filesWhen your PC is not shut down properly, it tends to pass data stored in memory into fragmented files. While youre running programs, your PC will write information that it does not directly require into temporary files. Files that have been installed will also increase themselves into the temporary folder or clean-up themselves.
