Windows Media Player Problems: How to Stop WMP Freezing in Full Screen Mode

How to stop Windows Media Player in Vista crashing when in full screen mode

By

If you have Windows Vista and find that Windows Media Player (WMP) freezes when you switch to full screen mode, then this is normally the fault of your graphics card being incompatible with this mode. Having Aero Glass disabled can also cause WMP to freeze or crash. Using a registry hack, you can quickly fix this problem and use WMP in full screen mode without the display freezing. To do this, follow these steps:

  1. Hold down the [Windows key] and press [R].
  2. Type in regedit and hit [Enter].
  3. Navigate to the following registry path: HKEY_CURRENT_USER\SOFTWARE\Microsoft\MediaPlayer\Preferences
  4. Click Edit > New > DWORD (32-bit) Value, type DXEM_UpdateFrequency and hit the [Enter] key.
  5. Double click on the new DWORD entry that you have just created, type in a value of 2 in the data field and click OK.
  6. Exit the Windows registry editor. When you switch to full screen in Windows Media Player you should now find that it doesn't freeze.
