With Windows 11, Microsoft replaced Groove Music with its modern and sleek-looking Media Player app, which is a significant improvement over its predecessor. However, like with any app, the new Media Player can also trouble you at times when it fails to open or work as expected.

Before you give up and look for an alternative, consider applying the following fixes to resolve issues with the Media Player app in Windows 11.

1. Check Your Media's File Format

Although Microsoft's latest Media Player is designed to work with nearly all the popular audio and video formats, it is not compatible with all of them. It’s possible that the media file you are trying to play is in an unsupported format, giving you the impression that the Media Player app is not working.

Hence, before troubleshooting the app, you should ensure that the file you are using is in a format that Media Player supports. You can verify the format of the file by checking its properties in Windows, then checking the supported Windows Media Player file types on Microsoft Support.

If you find that your file is unsupported, use a free online converter to change its format to a compatible one.

2. Enable Video Library Access for the App

The Media Player app may fail to show videos stored on your PC if you have inadvertently disabled video library access for the app. Here’s how you can enable it.

  1. Right-click on the Start icon and select Settings from the list.
  2. Use the left pane to navigate to the Privacy & security tab.
  3. Scroll down to click on Videos.
  4. Enable the toggles next to Video library access and Let apps access your video library.
  5. Turn on the toggle next to the Media Player app.

3. Refresh Your Libraries

If the Media Player app fails to detect your files even after enabling video library access, you can try refreshing the libraries. This will allow the app to scan your system for media files again.

To refresh libraries in the Media Player app, follow these steps:

  1. Open the Media Player app on your PC.
  2. Click the gear icon in the bottom left corner.
  3. Under Libraries, click the Refresh button.
    Refresh Libraries in the Media Player App

Switch to the Library tab and check if your media files appear now.

4. Disable Video Enhancements

Your Windows 11 PC ships with a video enhancement feature that can help improve your video playback experience. However, if your hardware isn’t compatible with these enhancements, you might have trouble playing videos. Hence, it’s best not to use them.

To disable video enhancements in Windows, use these steps:

  1. Open the Start menu and click the gear-shaped icon to launch the Settings app.
  2. Select the Apps tab on your left.
  3. Click on Video playback.
  4. Turn off the switch next to the Process video automatically to enhance it option.

5. Run the Relevant Windows Troubleshooters

If you’re facing playback issues in other media players as well, you can consider running Windows' troubleshooters. Specifically, you can run the Playing Audio and Video Playback troubleshooters. This will allow Windows to diagnose your system for any video playback issues and suggest fixes accordingly. Here’s how you can run these troubleshooters on Windows.

  1. Open the Windows Settings.
  2. In the System tab, click on Troubleshoot.
  3. Select Other troubleshooters.
  4. Click the Run button next to Playing Audio and follow the on-screen prompts to complete the troubleshooting process.
  5. Click the Run button next to Video Playback and allow it to do its thing.

After running these troubleshooters, restart the Media Player app and see if it works.

6. Repair or Reset the Media Player App

Windows 11 includes a useful app repair tool for fixing common issues with apps. You can use this feature to fix issues with most of your apps, including Media Player. Windows will scan the app’s files and settings during this process and attempt to fix any issues it discovers.

7. Re-Register the Relevant DLL Files

Dynamic Link Libraries (DLLs) files on your PC contain functions and data that programs use to perform specific tasks. If some of the DLL files linked with the Media Player app are missing or damaged, the app may fail to open or work. Here’s what you can do to fix them.

  1. Right-click on the Start icon or use the Win + X keyboard shortcut to access the Power User menu.
  2. Select Terminal (Admin) from the list.
  3. Select Yes when the User Account Control (UAC) prompt appears.
  4. Run the following commands one by one.
            regsvr32 vbscript.dll
    regsvr32 jscript.dll
    regsvr32 wmp.dll

Restart your PC after this and then check if the Media Player app works as before.

8. Update the Media Player App

Microsoft regularly pushes newer updates for the Media Player app to add new features, eliminate bugs and improve its performance. There’s a chance that the issues with the Media Player app are limited to the app version you are using. If that’s the case, updating to a newer version should help.

Check our guide on how to update apps in Windows 11 and use the steps provided there to update the Media Player app to its most recent version. Hopefully, this should solve your problem.
