VP9 Video Extensions Download: Install, Offline Installer & Fix Playback Issues

Part 1. VP9 Video Extensions Download from Microsoft Store for Windows 11/10

Before downloading, know that there are two main options: downloading from the Microsoft Store or using offline installers. For systems without Microsoft Store access, the VP9 Video Extensions without Microsoft Store method is ideal.

Common Download Sources:

• Microsoft Store: Official source for the VP9 Video Extensions Metro App (version 1.2.6.0 as of May 2025).

Download VP9 Video Extensions from Microsoft Store

• Open the Microsoft Store app on your Windows 10/11 device.

• Search for “VP9 Video Extensions” or visit the direct link: Microsoft Store VP9 Video Extensions.

  

• Click Get to download and install the VP9 Video Extensions Metro App. Sign in with a Microsoft account if prompted.

• Wait for the installation to complete, then test by playing a VP9-encoded video in the Movies & TV app.

Part 2. Install VP9 Video Extensions Using Offline Installer & Widget & Powershell (Without Microsoft Store)

If Microsoft Store is blocked, unavailable, or keeps failing to download VP9 Video Extensions, you can still install the codec without opening the Store app. This is useful for work computers, school PCs, restricted Windows environments, or users who receive Microsoft Store errors during installation.

There are three practical ways to install VP9 Video Extensions without using the Microsoft Store interface: using an offline installer, installing it with Winget, or reinstalling it with PowerShell when the extension is already broken or not working properly.

1. VP9 Video Extensions Offline Installer

If your device can’t access the Microsoft Store:

• Visit a trusted third-party site like Uptodown or Microsoft update catalog.

  

• Download the VP9 Video Extensions offline installer (e.g., Microsoft.VP9VideoExtensions_1.2.6.0_x64.appx).

• Open PowerShell as an administrator. Just right-click “Start” > select “Windows PowerShell” (Admin).

• Run the command: Add-AppxPackage -Path "C:\Path\To\Downloaded\Microsoft.VP9VideoExtensions_1.2.6.0_x64.appx" (replace with your file path).

• Press Enter to install and verify by playing a VP9 video.

If double-clicking the package does not work, you can install it manually with PowerShell. Right-click the installer file, copy its file path, then open Windows PowerShell as administrator and run:

Add-AppxPackage -Path "C:\Users\YourName\Downloads\VP9VideoExtensions.appxbundle"

Replace the example path with the actual location of your downloaded VP9 Video Extensions package.

Notes

Avoid downloading unknown codec packs or modified installers. For safety, use a reliable package source and make sure the installer is not bundled with unwanted software.

Method 2. Install VP9 Video Extensions with Winget

If your computer supports Windows Package Manager, you can install VP9 Video Extensions with Winget. This method does not require you to search for the extension manually in Microsoft Store, but it still uses the Microsoft Store source to get the package.

Follow these steps:

• Right-click the Start button.

• Choose Terminal (Admin), Windows PowerShell (Admin), or Command Prompt (Admin).

• Run the following command:

winget install --id 9N4D0MSMP0PT --source msstore

• Wait for the installation to finish.

• Close and reopen your video app or browser.

• Try playing the VP9, WebM, MKV, or MP4 video again.

This method is especially helpful when Microsoft Store opens slowly, cannot load the VP9 Video Extensions page, or keeps showing download errors.

Tips

If Winget is not recognized on your PC, your Windows version may not include Windows Package Manager, or it may be disabled by your organization. In that case, use the offline installer method instead.

Method 3. Reinstall VP9 Video Extensions with PowerShell

If VP9 Video Extensions is already installed but your VP9 or WebM videos still cannot play, the extension may be outdated, damaged, or not registered properly. Reinstalling it can help fix broken codec components.

First, check whether VP9 Video Extensions is installed on your PC. Open Windows PowerShell as administrator and run:

Get-AppxPackage *VP9VideoExtensions*

If the extension is installed, PowerShell will return package information such as the package name, version, and install location. If nothing appears, VP9 Video Extensions may not be installed.

To remove the current VP9 Video Extensions package, run:

Get-AppxPackage *VP9VideoExtensions* | Remove-AppxPackage

After the removal is complete, reinstall VP9 Video Extensions with Winget:

winget install --id 9N4D0MSMP0PT --source msstore

Once the installation is finished, restart your video player or browser and open the VP9 video again.

Notes

If the video still shows a black screen, has no sound, freezes, or cannot be opened after reinstalling VP9 Video Extensions, the issue may come from the video file itself rather than the codec. In that case, the VP9/WebM file may be corrupted. You can try repairing it with 4DDiG Video Repair before converting the video or reinstalling codecs again.

Part 2. What Is VP9 Video Extension & Do I Need It?

1. What does VP9 Stand For & VP9 Video Extension Meaning

VP9 stands for “Video Processing 9,” a royalty-free, open-source video coding format developed by Google. It’s widely used for online video platforms such as YouTube and Netflix, where it enables smooth, high-resolution video playback without using excessive bandwidth.

The VP9 Video Extension is a Microsoft-developed add-on that allows Windows apps — including Edge, Movies & TV, and third-party players — to decode VP9 content natively. It is part of the Microsoft Windows VP9 Video Extensions library and is available for free via the Microsoft Store or other sources.

Without this extension, users may encounter:

• Playback errors in web browsers when streaming VP9 content
• "Format not supported" messages in media players
• Audio-only playback with missing video streams
• Performance issues when accessing YouTube, Netflix, and other streaming platforms

2. Do I Need VP9 Video Extension?

Yes. You need it, especially if you encounter any of the following scenarios:

• You're trying to play VP9-encoded videos (.webm or .mkv) in Microsoft Edge or the Movies & TV app, but see playback errors.
• You use video editing or playback software that depends on system codecs.
• You want to watch 4K or 8K videos on YouTube without stuttering.
• Your hardware supports VP9 acceleration but lacks software decoding.

If you're running Windows 10 or 11 and care about streaming efficiency or modern media compatibility, having the VP9 Video Extension installed ensures better performance and fewer compatibility issues.
