OEM software is a full version (non-upgrade) which includes only the CD-ROM, the Certificate of Authenticity (COA), and the product key codes. These elements are all you need to load and run the software, and it will run exactly the same as the version that comes packaged in a box for retail. OEM software does not include a box or comprehensive manual. We only recommend OEM software if you are highly technically inclined, as it is not covered for technical support by the manufacturer. All OEM products are labeled as such. Please note that OEM products may not, in most cases, be used to upgrade from a previous version. However, OEM software is eligible for future upgrades.
