Full Packaged Product
A Full Packaged Product is boxed software like you would buy in a retail store. Full Packaged Products are intended for consumers who need to purchase a small quantity of software licenses. When you install the Full Packaged Product version of Windows XP Professional, Setup asks you to enter a product ID (a 25-digit code found on the product packaging) during installation. You must also activate Windows XP Professional after installation.

Original Equipment Manufacturer (OEM) and System Builder licenses are acquired when you buy a computer that already has software installed. Typically, you do not have to activate this type of license.

When a company has a volume license for Windows XP Professional, the installation files are typically made available for installation over the network. Product IDs and product activation are not required.
