I purchased Office 2007 or Office 2010 with my computer, but I don't have a CD.

Microsoft 2007 and 2010 products are shipped without a CD.

If you need to reinstall the software because you have had to reload your system, Microsoft Office system backup discs for medialess license kits are available through Microsoft.

Microsoft Office 2007

Microsoft Office 2010

Simply confirm your license by entering your Product ID Key and the options to download or to purchase media on CD will be presented.
