Why you might not want to upgrade to Windows Media Player 9
I didn't actually check the EULA for WMP 8, so perhaps this isn't new. However, I was surprised to see that the supplementary EULA contained the following details:
* Content providers are using the digital rights management technology contained in the OS Components ("DRM") to protect the integrity of their content ("Secure Content") so that their intellectual property, including copyright, in such content is not misappropriated. Portions of the OS Components and third party applications such as media players use DRM to play Secure Content ("DRM Software"). If the DRM Software’s security has been compromised, owners of Secure Content ("Secure Content Owners") may request that Microsoft revoke the DRM Software’s right to copy, display and/or play Secure Content. Revocation does not alter the DRM Software’s ability to play unprotected content. A list of revoked DRM Software is sent to your computer whenever you download a license for Secure Content from the Internet. You therefore agree that Microsoft may, in conjunction with such license, also download revocation lists onto your computer on behalf of Secure Content Owners. Microsoft will not retrieve any personally identifiable information, or any other information, from your computer by downloading such revocation lists. Secure Content Owners may also require you to upgrade some of the DRM components in the OS Components ("DRM Upgrades") before accessing their content. When you attempt to play such content, Microsoft DRM Software will notify you that a DRM Upgrade is required and then ask for your consent before the DRM Upgrade is downloaded. Third party DRM Software may do the same. If you decline the upgrade, you will not be able to access content that requires the DRM Upgrade; however, you will still be able to access unprotected content and Secure Content that does not require the upgrade.
Microsoft is slowly going to the model where the purchaser doesn't actually own their software or computer.
