What this feature does
Windows Media Player uses Microsoft Digital Rights Management (DRM) technology to preserve the rights of content owners who want to protect their music or video products. You must have the media usage rights to play, burn, or sync protected content.
If you subscribe to an online music or video subscription service available through Windows Media Player, software installed on your computer by the online store may request to obtain the usage rights before you can play the content. Windows Media Player will automatically scan the protected content for expired rights and request renewals from the rights server.
If you acquire protected content from a music or video store, you may receive the associated usage rights at the same time. If not, when Windows Media Player tries to use a protected file that has rights missing, it will try to acquire the rights for you.
Some protected content may required a DRM software component upgrade before it can play. Windows Media Player will request your consent to download and install updated software. If you decline the upgrade, you will be unable to use content that requires the DRM upgrade. However, you will still be able to use unprotected content and secure content that does not require the upgrade.
Many portable media players contain an internal clock that is used to validate current media usage rights to allow files to play on the device. Windows Media Player can automatically set the clock on your portable media player when it syncs content to the device.
Information collected, processed, or transmitted
Windows Media Player requests rights directly from a rights server on the Internet. The server's web address is specified in the protected content. Most rights servers are operated by companies other than Microsoft. If a DRM component needs to be upgraded to play protected content, the request for the component upgrade is routed to a Microsoft server.
When requesting rights or component upgrades, Windows Media Player will provide the server with standard computer information, an ID for the music or video file, the action you have requested (such as play or burn), information about the DRM components on your computer, such as their revision and security levels, and a unique identifier for your computer. The unique identifier is used only to generate the rights for your computer and, because it is enclosed in an encrypted license request, is not available to the rights server in a way that uniquely identifies you or your computer.
When setting the clock on a portable player, Windows Media Player sends a time inquiry to a WindowsMedia.com server that contains standard computer information, standard troubleshooting data, and a request for the current time.
Use of information
Rights servers provide renewed rights, which Windows Media Player will write into the protected files to allow them to be used. A list of revoked software can be sent to your computer when you acquire media usage rights. DRM software upgrades are provided by the Microsoft servers in the form of a link, which Windows Media Player uses to install the updated software.
Windows Media Player is considered a DRM software component, and thus could be a required upgrade to use some protected content. Revocation does not alter the ability of Windows Media Player to play unprotected content, but you will not be able to play revoked secure content until you update the Player to a more recent and secure version.
Portable players that support Microsoft DRM can be revoked if a security issue is found. If this occurs, your device will be unable to obtain new media usage rights. However, protected content that already plays on your device will still play.
Choice/control
If you chose the Recommended settings the first time you opened Windows Media Player, the Player will automatically try to acquire usage rights silently unless the server requires some input from you, such as registration information or a fee. You can prevent Windows Media Player from scanning the Library for files that need new usage rights by doing the following:
Click Organize, and then click Options.
Click the Privacy tab, clear the Automatically check if protected files need to be refreshed check box, and then click OK.
To prevent Windows Media Player from acquiring rights automatically when you use the file:
Click Organize, and then click Options.
Click the Privacy tab, clear the Download usage rights automatically when I play or sync a file check box, and then click OK.
To configure Windows Media Player to set the clock on a portable media player:
Click Organize, and then click Options.
Click the Privacy tab, select the Set clock on devices automatically check box, and then click OK.
Important information
Microsoft also provides a service that lets you move media usage rights for files that were copy-protected when they were ripped (or copied) to a computer. If you try to play these files on a different computer, Windows Media Player will open your default browser and send a webpage request to a migration server at Microsoft. The request will contain standard computer information, a unique ID for the computer that originally protected this content, plus information that identifies the new computer. Unless the migration limit was reached, new rights will be returned that enable use of the content on the new computer. Microsoft keeps track of the number of migrations granted and allows a limited number of migrations.
