When you click on this button, the Disk Cleanup program will restart and scan your hard drives again.

To enable them click on the Clean up system files button as indicated by the red arrow in the image above. The default Disk Cleanup screen does not allow you to remove system files, so we need to enable those options first. When it is done you will be shown the Disc Cleanup screen. It may take a few minutes to scan your drives, so please be patient. When the program launches it will perform a scan of your computer's hard drives to determine what files can be cleaned up and how much storage space they use. When the search result appears as cleanmgr.exe or Disk Cleanup, please click on that result to launch the program.

To access Disk Cleanup, type cleanmgr in the search field of the Windows Start Menu or on the Windows 8 Start Screen.

To delete these folders you can use a Windows tool called Disk Cleanup. Unless you have created a backup, these folders will be permanently deleted from your computer. Before deleting the backups of your old Windows folders, please make sure that you have all of your data migrated to the new version of Windows.
