Tap on the Windows-key if you are not on the start screen. Type Disk Cleanup and select "Free up disk space by deleting unnecessary files". Click on the button "Clean up system files". The application restarts and additional cleanup options are available. Look for the entries "Previous Windows installation(s)" - if you have upgraded from a previous version - and "Windows Update Cleanup". Select these and any others you want to clean. It is safe to select all available options. Note: If you select the above two options you will no longer be able to restore a previous version of Windows or a previous update. After running Disk Cleanup perform a system restart and then repeat the procedure, restarting again.
