1. Begin Date. This right specifies a date after which the license is valid. Before this date, the Windows Media file cannot be played.
2. Expiration Date. This right specifies a date after which the license is no longer valid and the Windows Media file can no longer be played. For example, you can set a license to expire on December 31, 2004.
3. Expiration After First Use. This right specifies the length of time (in hours) a license is valid after the first time the license is used. For example, you can set a license to expire 24 hours after a consumer begins to play the Windows Media file.
4. Expiration On Store. This right specifies the length of time (in hours) a license is valid after the first time the license is stored on the consumer's computer. For example, you can set a license to expire 72 hours after it is stored.
5. Delete On Clock Rollback. This right deletes the license if the consumer's computer clock is set to an earlier time. For example, you can use this right if the license also specifies an expiration date.
6. Disable On Clock Rollback. This right disables a license if the consumer's computer clock is rolled back. The license is enabled again when the clock is corrected.
