If you want to free up even more space on your PC, tap or click More Options and choose from the options:
Programs and Features. Uninstall programs you no longer use. The Size column shows how much space each program uses.
System Restore and Shadow Copies. Delete all but the most recent restore point on the drive. System Restore uses restore points to return your system files to an earlier point in time. If your PC is running normally, you can save space by deleting the earlier restore points. In some editions of Windows, restore points can include previous versions of files, known as shadow copies, and backup images. These files and images will also be deleted.
