    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!

    .jar files opening in internet explorer

    Hi Robert,

    Welcome to Microsoft Community.

    I understand that .jar files opens in Internet Explorer by default and downloads again on Windows 10. I will certainly help you.

    I suggest you to follow the below steps and check if it resolves the issue.

    1. Right click on the .jar file, select Open with
    and click on Choose another app.

    2. Select the app you want to open the .jar file from list.

    3. If required, highlight the app and check the option
    Always use this app to open, click OK.

    Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.
