What is OEM software?
OEM means “Original Equipment Manufacturer.” OEM software is a full version of a program used by system builders and computer manufacturers. It is identical to the Retail Box version, but does not include a manual, a box, or installation support from the manufacturer. Support is usually still available on the manufacturer’s web site or on a paid-per-incident basis. OEM versions will usually include the software in the form of a CD-ROM, the Certificate of Authenticity, the product key code, the license, and a registration card. If you buy a Microsoft OEM or DSP version that does not have all of these items, there is a good chance that the software is not authentic.
What is DSP software?
DSP means “Delivery Service Partner.” It is a version of OEM software used by smaller computer manufacturers and system builders.
What is the difference between OEM and DSP software?
The software in both OEM versions and DSP versions is the same. OEM software normally has the hardware manufacturer’s name, such as Dell or Sony, printed on the manual and license. DSP software, however, has NO manufacturer’s name stamped on the manual or printed on the license. DSP versions usually just say “OEM.” Basically, DSP is a more generic packaging of an OEM product that is sold to smaller system builders who do not qualify for larger volume discounts and custom printing on their software.
Please note that OEM and DSP non-operating system software (such as Microsoft Office, Works Suite, WordPerfect, etc.) cannot be installed over a previous version as an Upgrade.
