Windows Media Player 12 (WMP12) is the default and factory-installed media player that comes with Windows 7, and WMP12 does not have standalone setup installer available for free download. As such, Windows 7 users cannot uninstall and install Windows Media Player 12 manually. In fact, there is no entry of WMP12 in “Programs and Features” that allows uninstallation or removal.

There is chance that user may need to uninstall, remove and then re-install Windows Media Player 12, such as to fix WMP corruption (possibly due to attempt to downgrade or convert WMP12 to WMP11), or to reset and re-configure Windows Media Player.

For WMP 12 in Windows 7, here’s the steps to uninstall or re-install Windows Media Player and Windows Media Center (which will be removed if WMP is removed as it relies on WMP).

  1. Click on Start button, and open Control Panel -> Programs -> Programs and Features.
  2. Click on Turn Windows features on or off in the left pane.
