Can I uninstall Windows Media Player 10?
You can use either Add or Remove Programs or System Restore to roll back to the previous version of the Player that was part of your original version of Windows. To roll back from Windows Media Player 10 to a previous version using Add or Remove Programs, do the following:
In Control Panel (Category View), click Add or Remove Programs.
Click Add or Remove Programs again, and then do one of the following:
If you are running Windows XP Service Pack 2, select the Show updates check box (at the top of the list), click Windows Media Player 10, and then click Change/Remove.
- or -
If you are running Windows XP Service Pack 1 or earlier, click Windows Media Player 10, and then click Change/Remove.
To roll back from Windows Media Player 10 to a previous version using System Restore, see the Use System Restore to Undo Changes if Problems Occur Web page.
You can also remove access to Windows Media Player by using the Set Program and Access Defaults feature. Note that this only removes links to the Player. It does not remove the Windows Media Player software. To remove access to Windows Media Player, do the following:
In Control Panel, double-click Add or Remove Programs.
Click the Set Program and Access Defaults button, and then choose a configuration (such as "Non-Microsoft" or "Custom").
Som du kan se, kan du ikke fjerne Mediaplayer, men i visse tilfælde rulle tilbage til en tidligere version.
