Quick Note: Before You Begin

Before proceeding, make sure you have:

  • A stable internet connection to download updates.
  • Administrator access on your Windows 10 computer.
  • Backup of important data, just in case you need to reinstall software.
  • Closed all Java-based applications to avoid conflicts during updates.

Step 1: Check Your Current Java Version

Knowing your installed Java version helps determine if an update is necessary.

  1. Press the Windows key and type cmd.
  2. Click on Command Prompt to open it.
  3. In the Command Prompt window, type java -version and press Enter.
  4. You will see information about the installed Java version, such as java version "1.8.0_281".

If the command shows an error or no version, Java may not be installed or the PATH is not set properly. If the version is older than the latest available on the official Java website, you need to update it.

Step 2: Download the Latest Java Version

Updating to the latest Java version improves security and compatibility.

  1. Open a web browser and go to the official Java download page: https://www.java.com/en/download/
  2. Click on the Download button to get the latest Java installer.
  3. Save the installer file to a location you can easily find, like the Desktop or Downloads folder.

Downloading from the official site ensures you get a safe and up-to-date version without any unwanted software.

Step 3: Uninstall Old Java Versions

Removing old Java versions helps prevent conflicts and frees up space.

  1. Press the Windows key and type Control Panel, then open it.
  2. Click on Programs, then select Programs and Features.
  3. Look for any entries starting with Java or JRE.
  4. Select the old Java version(s) and click Uninstall.
  5. Follow the on-screen prompts to complete the uninstallation.

Keeping only the latest Java version avoids version conflicts and potential security risks.

Step 4: Install the Latest Java Version

Now that old versions are removed, install the new Java.

  1. Double-click the Java installer you downloaded earlier.
  2. Follow the installation wizard’s instructions step-by-step.
  3. Choose the default settings unless you have specific needs.
  4. Wait for the installation to complete, then click Close.

Installing Java correctly ensures that your system is using the latest features and security patches.

Step 5: Verify the Java Update

After installation, double-check that the update was successful.

  1. Open Command Prompt again (see Step 1).
  2. Type java -version and press Enter.
  3. Confirm that the displayed version matches the latest version you installed.

This verification step confirms that your Windows 10 system recognizes the newest Java version.

Alternative Method: Use Java Control Panel to Update

If you already have Java installed but want to update without reinstalling manually, use the Java Control Panel.

  1. Press Windows key + S and type Configure Java, then select the Java Control Panel.
  2. Switch to the Update tab.
  3. Click Update Now to check for the latest version.
  4. If an update is available, follow the prompts to download and install it.

This method is useful for keeping Java up to date automatically through the built-in updater.
