A retail copy is one that you would buy in a typical store. It usually comes with technical documentation, has less restrictive licensing, and costs more. An OEM version costs less, has less documentation, and usually limits you in your ability to transfer the product from one computer to the other.

Retail software: This type of software is sold off the shelves of retail stores. It includes expensive packaging designed to catch the eye of shoppers and, as such, is generally more expensive. An advantage of retail software is that it comes with printed manuals and installation instructions, missing in hard-copy form from virtually every other category of software. However, when hard-copy manuals and instructions are not required, a down loadable version off the Internet will be less expensive, if available.OEM software: OEM stands for "Original Equipment Manufacturer" and refers to software sold in bulk to resellers, designed to be bundled with hardware. For example, Microsoft has contracts with various companies including Dell Computers, Toshiba, Gateway and others. Microsoft sells its operating systems as OEM software at a reduced price, minus retail packaging, manuals and installation instructions. Resellers install the operating system before systems are sold and the OEM CD is supplied to the buyer. The "manual" consists of the Help menu built into the software itself. OEM software is not legal to buy unbundled from its original hardware system.

OEM. eg. Dell OEM Windows.
The difference between an OEM controller and a non OEM controller is that an OEM controller is made by Microsoft. A non OEM controller is made by other companies. OEM stands for Original Equipment Manufacture.
Windows 7 OEM Editions don't come in pretty boxes like Windows 7 Full Retail does, nor do they come with any manuals or documentation. The software found on the disc is the same as the one found on the Full Retail copy. The only real difference is that OEM Software cannot be returned once opened, and there are no exceptions. OEM Software is also tied to the motherboard it is first installed on, which means if you ever wanted to change your motherboard because you were upgrading your computer, you would have to buy a new version of Windows, because the one you have is only going to work with that motherboard, unlike the full retail version which can be transferred to a new computer; OEM versions cannot be transferred. So, when asking if OEM is better than the Windows 7 Upgrade; technically, OEM can only be used on one motherboard and the upgrade can only be used on one Windows 7 that is already activated, and once you use the upgrade, it's no longer useful anymore. I would have to say that the OEM is definitely better than the Windows 7 upgrade, because you can at least use the OEM more then once in case something ever happens with your operating system plus the upgrade is only good if you have a Windows 7 already installed.
Here is a good description of Retail, Bare, OEM, and Bulk (Brown / White box): http://www.googlegear.com/ggweb/jsp/Service/OEM.jsp Product Version/Packaging: Retail, Bare, OEM, Bulk (White/Brown Box) Retail The "Retail" version of a product is what you would expect to see on a store's shelf. It is intended for an end-user, and is usually packaged in a fancy box along with a user's manual and sometimes "extras" such as a software bundle. Bare Products Drives are usually the only products that we might sell as "bare." Bare drives have a great price, but do not come with cables, drivers, or other software--unless stated otherwise. In addition, generally bare drives are packaged only in an antistatic bag, not a box, and come with minimal or no user instructions. In many cases, however, a user's manual can be downloaded from the manufacturer's website. (If you require a user's manual we recommend that you double check that before you buy.) OEM & Bulk Pack products The Bulk and OEM versions of a product also have some variations from the retail version, but usually a much better price. If you are considering a bulk or OEM version, it is a good idea to compare specifications with the retail version to find out exactly what the differences are. There is one difference that is fairly consistent, however, and that is the packaging. Bulk and OEM products do not come in fancy packaging. They may come in a plain White Box or Brown Box, or simply in anti-static wrap or plastic. Most common differences between OEM & Retail (Note! Sometimes these differences apply to Bulk products too.) OEM products may come with an abridged or no user's manual. If you order an OEM product and find you need more installation information, you can usually get what you need from the manufacturer's website. OEM products may not come with a software bundle. Customers who opt for OEM in such a situation sometimes prefer a different type of software than the one bundled, or may feel they will not use the software (such as a game). Many manufacturers will not offer full technical support to end users who have purchased OEM products. Part of what you pay for when you purchase retail hardware is technical support, should you need it. That cost is not included in the price of OEM products. An OEM product may have a different warranty period. This is not normally the case, except with CPUs. Usually the retail version of a CPU has a 3 year warranty, while the OEM version's warranty only lasts between 30 days and 1 year. The Bottom Line Purchasing a bulk or OEM product is a great way to save money--especially if you are knowledgable about computers. Just make sure you understand how the product differs from the retail version.
This is the full OEM version with DVD and COA with the key code. OEM software does not include phone support from the manufacturer.
Nothing. OEM and Retail are exactly the same. The OEM version is really intended for original equipment manufacturers who would purchase a licence and a disc containing the operating system. They would then supply their own disc containing a copy of the operating system along with their own customisations (banners and support tools) as well as 3rd party software bundles to keep the cost down. Most OEMs don't even supply a disc, they simply supply the OEM licence and place a copy of the disc on a hidden partition of the hard-drive from which the end-user can create a recovery disc after the initial installation is complete.
Not if you bought a retail copy.

OEM stands for original equipment manufacturer. Software, especially versions of the Windows Operating system, can often be provided as an OEM version. That means it's designed and licensed to be supplied already loaded onto a new computer by the manufacturer. With an OEM version, there is no support from the software company - the equipment manufacturer is expected to provide that. Usually there is no printed literature although the manual is provided as a computer file. Buying an OEM version is usually much cheaper than the retail version, although if you didn't build the machine, you're contravening the licence terms. If it goes wrong, you're on your own!
