Installing & Removing Windows Media PlayerBefore you install Windows Media Player 11, do the following:
Go to Windows Update and install any high-priority updates that are available for your computer.
If you have a Creative ZEN device, see Issues updating firmware on Creative ZEN portable devices after installing Windows Media Player 11.
Save media information and ratings to your media files. Perform the steps in the following procedure to save media information and star ratings to your media files.
1. In Windows Media Player 10, click the Tools menu, and then click Options.
2. Click the Library tab, select the Maintain my star ratings as global ratings in the media files check box.
When this check box is selected, the user ratings for your songs are saved in your media files rather than in your library database file. This process occurs in the background, so it may take some time before your ratings are saved to all of your media files.
The next step in this procedure ensures that your ratings (and any changes that you have made to other media information) are saved to your files immediately.
3. Click the Tools menu, and then click Process media information now.
Back up your existing data. To use the Backup Utility in Windows XP, click Start, point to All Programs, point to Accessories, point to System Tools, and then click Backup.

Note:
If you remove Windows Media Player 11 and the Windows Media Format 11 Runtime, and then encounter error C00D271D ("A problem has occurred in the Digital Rights Management component.

For information about installing the Runtime, in the Microsoft Knowledge Base, see article 891122, "Update for Windows Media Digital Rights Management-enabled players."
You might not be able to roll back to a previous version of the Player if the hidden folder $NtUninstallwmp11$ is deleted from your computer. Some non-Microsoft programs (such as CCleaner) delete this folder in an attempt to remove unwanted files from your computer.
