21407 ...... Let me attempt to explain.......
OEM stands for Original Equipment Manufacturer.
In the case of XP Pro , ......It is produced by MicroSoft.
It only contains ..... The Windows XP Pro operating system.
The Retail and OEM versions are the same , the differance being, the license fee that is paid. Further, the OEM version doesn't include telephone
support at no cost.
I trust this helps .
