What is the difference between OEM (Original Equipment Manufacturer) software and retail (Full Packaged Product)?
OEM software is licensed for use only on the computer system on which it was installed originally. However, retail software may be transferred, in its entirety, to a different computer system as long as the person transferring the software deletes all copies of the software from his personal computer. Another difference is the identity of the licensor; for retail software, the license agreement is between Microsoft and the end customer. For OEM software, the license agreement is between the PC manufacturer and the end customer.
