OEM (Original Equipment Manufacturer) software is one that is distributed with computer hardware such as printers and cameras, or the actual computer itself. OEM software is often a limited or older version of a software that is sold as a stand alone product in order to provide users with what they need to work with specific hardware. However, users are still encouraged to purchase the unlimited, fully functional version. An example of fully functional OEM software is operating system software, which is generally sold as a complete product without limitations.

How OEM Software Works
OEM software is sold with virtually every type of computer hardware in existence. For example, the installation disc that comes with a webcam is a type of OEM software. The OEM software disc includes all of the installation files necessary to install the hardware on the user’s computer and allows the computer to see the device. The OEM software also includes the End-User License Agreement and any other legal documents that the user must read before installing it.

Applications
OEM software can be made for any type of electronic device that can be connected to a computer. In fact, OEM software can even be bundled with other software packages in order to properly install the software and present the user with the End-User License Agreement. While most OEM software comes from the product manufacturer, software pirates who copy the OEM software for any particular product often sell it illegally on the Internet for less than the manufacturer does.

Advantages
While most users usually overlook OEM software, it does have several advantages. For example, OEM software allows users to install, uninstall, and repair software and hardware devices. OEM software also includes all of the legal documents that the user must read before installing a device. Likewise, OEM software ensures that the user has a legal copy of all software and hardware that is installed on his/her computer.

Disadvantages
OEM software takes up more space on the user’s computer than the device software. OEM software purchased on the black market may also be contaminated with viruses or other unwanted software.
