This may require saving data locally on your device. As a user, at any given time can download or otherwise obtain this type of media while using Edge (HTML) browser, the Let sites save protected media licenses on my device setting assumes importance since it allows sites that offer this type of protected media to save DRM data on your device, including a unique identifier (ID) and media licenses (which make sure you have permission to access the media).This information is then retrieved by the websites a user visits that host the protected content in order to allow him to use that content. This setting in Windows 10 is turned ‘on’, by default. To change this setting, Open Edge and go to More actions > Settings.

To clear the DRM data, including your unique ID and any acquired media licenses, go to More actions More actions > Settings, and under Clear browsing data, select Using Windows Registry Open Registry and navigate to the following key: In the right pane of Privacy registry key, double click on EnableEncryptedMediaExtensions.
