The way to get it is different: there are two types of originals and ghost on the Internet. The installed version generally refers to the original version, the original version and ghost can be searched and found on the network, and the OEM system belongs to the factory pre-installed system, and the manufacturer will not share the OEM system on the network, which will violate the agreement with Microsoft and infringe copyright.

The content is different: the original system is the same as the genuine CD, and the OEM system will add the manufacturer's software on the basis of the original.

The authorization is different: the OEM system has been authorized from the factory, and the manufacturer buys it from Microsoft, while the original version will not be automatically activated after installation, and a key needs to be purchased.

OEM is an activation serial number that is purchased in large quantities by the manufacturer, and the verification method is different. The activation code of retail is the activation code of the retail version, which is the kind of thousands on the market. There is no stable and unstable place, but the activation method is different, and the OEM activation code can only activate the OEM, which is the system pre-installed by many manufacturers.

retail is the activation of the retail version.

Win7 OEM key and Retial key, the former is the installation key provided by the computer brand pre-installed Win7, the latter is the retail version of the Win7 installation key, the two are only different in the activation path, OEM uses BIOS activation, that is, the activation and software license are embedded in the BIOS, after installing Win7, as long as the BIOS is detected that there is a certificate of the brand, it will be automatically activated. The retail version of win7 requires an internet connection** to activate.

There are still differences, the content of the original image file is complete and reliable, and the installation process is not a long time to drive or something to update, no unnecessary operations are required. OEMs can't be said to be bad, but there are still limitations, such as the need for a specific computer, and key activation is cumbersome.
