How to Open JAR Files on Windows 10 and 11

To open JAR files on Windows 10 and 11, follow these steps:

  1. Make sure you have Java installed on your computer. If you don’t have it, you can download it from the official website.
  2. Right-click on the JAR file you want to open.
  3. In the context menu that appears, click on “Open With”.
  4. Select “Java(TM) Platform SE binary” from the list of available programs. If you don’t see it, click on “More apps” and scroll down to find it.
  5. If you want to always open JAR files with Java, check the box that says “Always use this app to open .jar files”.
  6. Click “OK” to open the JAR file with Java.

Alternatively, you can open JAR files from the command prompt:

  1. Open the command prompt by typing “cmd” in the Windows search bar and selecting “Command Prompt” from the results.
  2. Navigate to the directory where the JAR file is located using the “cd” command.
  3. Type “java -jar filename.jar” (without the quotes) and press Enter. Replace “filename.jar” with the name of the JAR file you want to open.
  4. The JAR file should now open in a new window.

These are the steps to open JAR files on Windows 10 and 11 using either the context menu or the command prompt.
