Setting Rights
Rights specify how a consumer can use a Windows Media file and define any other actions that are allowed, such as allowing the consumer to play the Windows Media file on a computer. Rights can also specify conditions for the license and media players, including devices. For example, you can set an expiration date for a license, after which the license is not valid and the Windows Media file can no longer be used.
A license is deleted when it expires, when all counted operations (such as the number of plays) are used, or when the corresponding packaged files are revoked. For example, if a license allows 10 plays, it is only deleted after the Windows Media file has been played 10 times. If a license has both counted operations and an expiration date, the license is deleted after all the counts have been used or the license expires, whichever comes first.
