OEM means "Original Equipment Manufacturer". OEM software is sold
directly to the computer manufacturer, or is distributed for
smaller system integrators and system builder hobbyists for “clone”
or no-name computers (to end user like you). OEM versions come with
only an electronic help manual, which is built-in to the software
or a small getting-started manual. The software itself contains the
same programs as the Retail Box version, except the Retail Box
version normally comes with a small printed manual & with fancy
retail box. Beside, OEM Software does not included Microsoft free
tech support since it's intent for user with in-depth knowledge to
install operating system. OEM Microsoft software include a COA,
which is a Certificate Of Authenticity label or sticker from the
manufacturer, plus key code for you to key in during installation,
and for your system to be activated/registed with Microsoft in
order to receive Windows Update Such as Internet Explorer 7,
Windows Defender, Media Player 11, and so on.
