If you want to upgrade the windows media player security component it might happen that the “upgrade” button is inactive. This will clear the cache and allow the IE to upgrade the Windows Media Player Security Component.
You will need this update to play protected songs, films or other digitally protected software. First of all, I would check if Active X is properly running because sometimes it’s not fully working. Make sure to access the site through your Internet Explorer instead of Firefox, because it simply won’t work.
Microsoft will then upgrade the security components of your digital media player to ensure that it runs with optimal security.
Progress Status: The security components have been upgraded successfully.
To play protected files, restart your digital media player.
If you cannot play protected files after restarting your digital media player, restart your computer.
Note: When you click Upgrade, your computer will connect to a Microsoft-operated Internet site and send information about your digital media player, including a unique hardware identifier.
