A new COA label began shipping on September 1, 2007. Note that the prior COA will still be in the market for some time, so please familiarize yourself with both versions. See below for details.

The Hologram
The face of the CD features a hologram—a three-dimensional image of objects—that displays both the name of the software program and a specific image related to that program. Beginning in August 2004 with the release of Windows XP SP2, the CD has the following characteristics:
See How to Tell on the Microsoft Web site for more information on holograms.
The inner mirror-band hologram is an optical band that wraps 180 degrees around the inner portion of the back of the disc. It is etched and embedded into the surface of the CD during manufacturing. The hologram, when tilted in the light, displays text that switches from "Microsoft" to "Genuine" and from "Secure" to "Media."
Individual OEM System Builder Windows software licenses must be distributed with the following:

Don't fall victim to standalone COAs. If you receive offers for COAs as standalone items, be aware that these offers are highly suspect—and they can put you and your customers at risk. If you fall victim to standalone COAs, you will have wasted money and your customers will not have a legal license to run their software.
Protect your customers and your company. Purchase software through a Microsoft authorized OEM distributor, an assured source of genuine Microsoft software.
The Anti-Counterfeiting Act of 2003 (U.S. only), passed on December 24, 2004, makes it a criminal offense to distribute standalone COA labels. There is now a significant legal risk for dishonest resellers to illegally deal in standalone COAs. The full weight of the law is behind the efforts of Microsoft to make the marketplace safe for your honest partners.
