How to Uninstall KMPlayer

KMPlayer is a versatile multimedia playback software developed by PandoraTV (now KMP Media Co., Ltd.). It supports a wide array of audio and video formats, including AVI, MKV, MP4, FLV, and even some less common ones such as RMVB and ASF. The application also features customizable skins, internal codecs, and the ability to play damaged or partially downloaded files. Despite its functionality, users may choose to uninstall KMPlayer due to interface preferences, system performance considerations, or the desire to switch to alternative media players. This article presents several methods for completely removing KMPlayer from Windows systems, with specific attention to differences between 32-bit and 64-bit operating systems, as well as compatibility nuances between Windows 10 and Windows 11.

Method 1: Uninstall KMPlayer via Control Panel (Windows 10/11)

Steps:

1. Press Windows + R to open the Run dialog box.
2. Type appwiz.cpl and press Enter to access the Programs and Features window.
3. Locate KMPlayer in the list of installed applications.
4. Right-click on it and select Uninstall.
5. Follow the on-screen prompts to complete the removal process.

Key Points and Notes:

• Ensure you are logged in with an administrator account.
• On 64-bit systems, KMPlayer may appear twice—once under “Programs and Features” and once under “Programs and Features (x86)”. Both entries should be uninstalled if present.
• In Windows 11, this method remains functionally unchanged, although users can also navigate through Settings > Apps > Installed apps to initiate the uninstallation.

Disadvantages:

• This standard method often leaves behind registry entries, temporary files, or configuration data.
• Some versions of KMPlayer install additional components such as update services or third-party toolbars that may not be removed automatically.

Success Rate:
Approximately 70% complete removal, depending on installation options and system configuration.

Method 2: Use the Built-in KMPlayer Uninstaller Tool

KMPlayer includes a native uninstaller executable within its installation directory, which may provide a more thorough removal than the Control Panel method.

Steps:

1. Navigate to the default installation folder:

• For 32-bit systems: C:\Program Files\KMPlayer
• For 64-bit systems: C:\Program Files (x86)\KMPlayer or C:\Program Files\KMPlayer (if a 64-bit version was explicitly installed)

1. Look for the file named uninst.exe or uninstall.exe.
2. Double-click the file and follow the on-screen instructions to remove the program.

Key Points and Notes:

• This method often removes more residual files and folders than the Control Panel approach.
• If the uninstaller fails to run, check for possible corruption in the installation directory or consider rebooting before retrying.

Disadvantages:

• The uninstaller may be missing or non-functional if the installation has been partially removed or corrupted.
• Does not guarantee removal of all registry keys or temporary user data.

Success Rate:
Approximately 80%, assuming the uninstaller is accessible and the installation is intact.

Method 3: Uninstall via PowerShell or Command Prompt

Advanced users may prefer using command-line tools to forcefully remove KMPlayer, especially when GUI-based methods fail or when dealing with incomplete installations.

Steps:

1. Open PowerShell or Command Prompt as Administrator.
2. Enter the following command:

   wmic product where name="KMPlayer" call uninstall

3. Confirm the action when prompted.

Key Points and Notes:

• This method works best with MSI-based installations.
• It bypasses graphical interfaces and directly interacts with the Windows Installer service.

Disadvantages:

• Requires technical knowledge and careful execution.
• May not work with portable versions or custom installations.

Success Rate:
Around 65%, depending on how the software was originally installed.

Conclusion

Uninstalling KMPlayer can be accomplished through various approaches, each with its own set of advantages and limitations. The Control Panel method provides simplicity but often fails to remove all traces of the application. The native uninstaller tool included with KMPlayer improves upon this but may not always be available or functional. Command-line methods offer flexibility and control but demand technical expertise and may not succeed with all types of installations.

Among these, using a third-party uninstaller like Perfect Uninstaller stands out as the most effective and reliable option, particularly for ensuring total removal of the application along with any leftover configurations or registry entries. From a professional standpoint, employing a trusted third-party uninstaller is highly recommended when seeking a clean system environment after software removal.

It is essential to maintain system integrity and security throughout the uninstallation process. Users should always create a system restore point and back up critical data before performing major system modifications. Proper maintenance and cautious handling of system-level changes will help preserve performance and stability over time.
