Cleaning the system is a tricky part in which you need to dig into the Windows folders and remove system garbage, which clutters the OS. There is also an additional step to clean the browser and remove old programs (or applications). Let's start with the simplest part, which is also much faster - cleaning the system.

  • Type "Disk Cleanup" in the search bar and press Enter;

  • Click Start, select Control Panel / Appearance and Personalization.
  • Select "Folder Options", then the "View" tab.
  • In the "Advanced Settings" section, select "Show hidden files, folders and drives" and click "OK."
  • Open \ Users \ $ USER $ \ AppData \ Local \ Microsoft \ Windows \ Temporary Internet Files (Where $ USER $ is your username).
  • Clear the folder by selecting the entire contents and deleting it.

  • Open the Start menu;
  • Locate Settings / System / Storage / Locate local storage called This PC;
