Microsoft also released retail packaging for Anytime Upgrade. The retail products were made available during the consumer launch of Windows Vista on January 30, 2007. The initial version of these products included only an upgrade license, but this was later modified in May 2007 to include both a DVD and a product license. In an effort to streamline the upgrade process, Microsoft announced that digital license distribution would cease on February 20, 2008; licenses purchased prior to this date would not be affected. As a result of this change, users would be required to purchase the aforementioned retail packaging in order to use Anytime Upgrade functionality and Windows Vista Service Pack 1 omitted the option to purchase a license online. DVDs for Anytime Upgrade were only produced for Windows Vista.
