Windows 10: There are exactly zero reasons why Windows Media Player should sieze control of .jar files

And yet it does. And when it does, Windows offers no mechanism to change it back. The Java runtime is not an option in app defaults settings. This can be fixed by downloading and installing the JRE again, but when it happens IN THE MIDDLE OF CLASS, that takes a ridiculous amount of time. Why on Earth would Windows think that a .jar file is media? No reason I can think of.

Hi,

Thank you for posting on Microsoft Communities.

What is the exact error message you get when you to try play files on Windows Media Player?

I suggest you to run both Windows Media Player Library and Settings troubleshooter and check.

Step 1: If your computer is having problems playing video or audio files in Windows Media Player, try using the Windows Media Player Settings troubleshooter to fix the problem. The troubleshooter checks the configuration and network settings
for Windows Media Player to make sure that you can play content you've downloaded and saved to your computer, or content streaming over a network or the Internet.

Steps to run Windows Media Player Settings troubleshooter are as follows:

• Press Windows key + X and select Control Panel.
• In the search box, type troubleshooter, and then click
  Troubleshooting.
• Click View all, and then click Windows Media Player Settings
  and follow the instructions.

Step 2: If your computer is having problems accessing your collection of digital media files in the Windows Media Player Library, try using the Windows Media Player Library troubleshooter to fix the problem. The troubleshooter makes sure
Windows Media Player is correctly installed on your computer, and checks to see whether your Player Library is corrupted.

Steps to run Windows Media Player Settings troubleshooter are as follows:

• Press Windows key + X and select Control Panel.
  
• In the search box, type troubleshooter, and then click
  Troubleshooting.
• Click View all, and then click Windows Media Player Library
  and follow the instructions.

jar files

Fixing .jar file opening on Windows requires two steps:

• Open the Control Panel, and chose "Default Programs - Associate a File type or protocol with a program". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)".
  A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button.
• Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. This is normally: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

I Hope this Answers your Question!
