How to Delete the “Windows.old” Folder in Windows 8 and 8.1

If you performed a refresh of Windows 8, upgrade to Windows 8, or a custom install of Windows 8 without formatting the drive for a clean install and selected to install Windows 8 on the same partition of the previous Windows installation, then you may have a C:\Windows.old folder left over in your new installation. The Windows.old folder contains a copy of the previous Windows installation, and can be quite large in size.
