Windows 10: The new media player app goes missing after installation.

I have installed the new Media player from Windows store at least 10 times. Each time it is available normally for a day or so. After that it somehow goes missing and I can't find a trace of it. On windows store page, it again asks to be installed. Any idea how it is automatically uninstalled?OS Name Microsoft Windows 11 Home Single Language Version 10.0.22621 Build 22621 Other OS Description Not Available OS Manufacturer Microsoft Corporation System Manufacturer HP System Model HP ENVY x360 Convertible 13-ay1xxx System Type x64-based PC System SKU 54B71PA#ACJ Processor AMD Ryzen 5 5600U with

Windows Media Player is not in Default apps list in Windows 10

I know, this question was asked many times, but there is still no answer that can actually solve the problem. There are steps to get the WMP in Windows Optional Features, install it if missing, etc. - I did all that, and now WMP runs and plays media files. However, there is no way in Windows 10 to set it as a Default App to play media file types.

• Go to "Default apps" > "Music Player" > "Choose Default" - WMP is not there.
  
• "Choose default apps by file type" > ".mp3" > "Choose a default" - WMP is not there.
  
• "Set Defaults by app" > Windows Media Player is here! > select "Manage" > find ".mp3" > "Choose a default" - the only choice is "Look for an app in the Microsoft Store".
  

After a long time spent searching I found this article: https://www.ghacks.net/2016/02/16/how-to-make-any-program-the-default-on-windows-10/

Apparently after 1803 you are supposed to use hackers tools to set the Microsoft's own Windows Media Player as default. I used FileTypesMan as was suggested in the article, but when I try to change assignments for .mp3 files, I get "Error 5: Access is denied" from the tool. Also, if I right-click on an .mp3 file and select "Open with..." it still suggests me to go to Microsoft Store, open with Notepad, Paint, Word, but not Windows Media Player.

What is the proper way to make WMP the default media player, so it shows up in the Default apps list?

New Windows Media Player Plugin for Firefox

Anyone who uses Windows Vista and Mozilla Firefox may be pleased to hear that the Windows Media Player team has now released a plugin for Firefox that should allow the browser to play WMP content on websites. Here are the steps to get it working:

• Installation of the Windows Media Player Firefox Plugin may require administrative access to your PC. It is recommended that you close all other open browser windows before continuing with the installation.
• Click the Install button to automatically download and install the Windows Media Player Firefox Plugin.
• Depending on your security settings, you may see a Security Warning dialog box. Click Install to install the plugin.

There is a known issue if you are using Firefox version 2.0.0.3 on Windows Vista with the installer failing with error code -203. To work around this simply restart Firefox (you will get a notification that Windows Vista will be changing the Firefox compatibility settings) and then install again - the second time should succeed.

The download is available here, and the new plugin works on all versions of Windows XP and Windows Vista (although it is mostly intended for Vista, as that currently has no WMP support in Firefox).
