How to Update Java Version in Windows 11

If you’re running an older version of Java on your Windows 11 PC, it’s a good idea to keep it updated. Java updates often include performance improvements, new developer features, and most importantly, security patches that protect your system from vulnerabilities.

In this guide, we’ll show you how to check your current Java version, update it to the latest release, and verify the installation — all in a few simple steps.

Why You Should Update Java on Windows 11

Before jumping into the steps, here’s why keeping Java up to date is essential:

• Security: Each new release includes fixes for critical security flaws.
• Performance: Updates often optimize the JVM (Java Virtual Machine) for better speed and memory usage.
• Compatibility: Many apps and IDEs (like IntelliJ IDEA, Eclipse, and Minecraft) require newer versions.
• New Features: Latest language features and APIs enhance your development workflow.

If your system still runs an older version like Java 8 or Java 11, it’s time to upgrade to Java 21 (LTS) or Java 25 — the latest available version.

Step 1: Check Your Current Java Version

Before updating, you should check which version of Java is currently installed.

1. Press Windows + R, type cmd, and hit Enter.

2. In the Command Prompt window, type: java -version

3. You’ll see output similar to:

java version "17.0.2" 2022-01-18 LTS
Java(TM) SE Runtime Environment (build 17.0.2+8-LTS-86)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.2+8-LTS-86, mixed mode, sharing)

If the version is older than Java 21 or 25, you should update it.

Step 2: Uninstall the Old Java Version (Optional but Recommended)

It’s usually a good idea to remove older Java installations to prevent conflicts.

1. Press Windows + I to open Settings.
2. Navigate to Apps → Installed apps.
3. Search for “Java” in the list.
4. Click the three dots next to the old version and select Uninstall.

You can also use Control Panel → Programs and Features to uninstall Java.

Step 3: Download the Latest Java Version

Now, let’s get the newest version of Java for Windows 11.

1. Go to the official Oracle Java download page: https://www.oracle.com/java/technologies/downloads/
2. Scroll down to Java SE Development Kit 25 (or latest).
3. Under the Windows tab, choose the correct installer:
   • x64 Installer for standard 64-bit PCs
   • ARM64 Installer for ARM-based Windows devices
4. Accept the license agreement and download the installer.

Tip: You can also use OpenJDK distributions like Adoptium Temurin or Amazon Corretto — both are reliable and free alternatives to Oracle JDK.

Step 4: Install the New Java Version

Once the installer is downloaded:

1. Double-click the downloaded .exe file.
2. Click Next to begin the setup.
3. Choose the default installation path: C:\Program Files\Java\jdk-25
4. Wait for the installation to complete, then click Close.

The latest Java version is now installed, but we still need to ensure your system recognizes it.

Step 5: Set the New JAVA_HOME Path (If Needed)

If you had an older version installed before, you might need to update the JAVA_HOME environment variable.

1. Press Windows + S and type Environment Variables.
2. Select Edit the system environment variables.
3. Click Environment Variables → New (under System variables).
4. Add:
   • Variable name: JAVA_HOME
   • Variable value: C:\Program Files\Java\jdk-25
5. Click OK to save.

Then, update the Path variable:

1. In the same window, select Path → Edit.
2. Click New and add: %JAVA_HOME%\bin
3. Click OK on all windows.

Step 6: Verify the Update

To confirm that Java is updated successfully:

1. Open Command Prompt again.
2. Type: java -version
3. You should see:

java version "25.0.0"
Java(TM) SE Runtime Environment (build 25.0.0+0)
Java HotSpot(TM) 64-Bit Server VM (build 25.0.0+0, mixed mode, sharing)

This confirms that your Windows 11 system is now running the latest version of Java.

Wrapping Up

Updating Java on Windows 11 ensures your system stays secure, fast, and compatible with the latest development tools. By following the steps above — from checking your version to installing and verifying the latest release — you can keep your Java environment running smoothly.

Whether you’re a developer, student, or just someone running a Java-based app, keeping Java up to date is one of the simplest ways to avoid compatibility issues and security risks.
