How to Install JRE in Windows 10: A Step-by-Step Guide for Beginners

Installing Java Runtime Environment (JRE) on Windows 10 is a straightforward process that involves downloading the installation package from the official Oracle website, running the installer, and configuring your system to use JRE. This guide will walk you through each step, ensuring you have Java up and running in no time.

How to Install JRE in Windows 10

Getting JRE set up on your Windows 10 machine is crucial for running Java applications, whether you’re coding or simply enjoying apps built with Java. The following steps will help you install JRE quickly and efficiently.

Step 1: Download the JRE Installer

Head to the official Oracle website and download the JRE installer for Windows.

When you visit Oracle’s website, you’ll see various Java downloads. Ensure you select the correct version for your system (usually indicated by your operating system and architecture, e.g., Windows x64).

Step 2: Run the JRE Installer

Locate the downloaded JRE installer file and double-click it to start the installation process.

When you run the installer, you might see a security warning. Click "Run" to proceed. The installer will then begin the setup wizard.

Step 3: Follow the Setup Wizard

Complete the installation by following the prompts in the setup wizard.

The setup wizard will guide you through the installation steps. Usually, the default settings are fine, but you can customize the installation directory if necessary.

Step 4: Verify the Installation

Open Command Prompt and type java -version to verify the installation.

If JRE has been installed correctly, you’ll see details about the Java version you installed. If not, the command prompt will inform you that Java is not recognized.

Step 5: Set Environment Variables (Optional)

Set environment variables to ensure Java is recognized system-wide.

This step is optional but recommended for developers. Go to Control Panel > System > Advanced system settings > Environment Variables. Add a new system variable JAVA_HOME and set its value to the JRE installation directory.

After completing these steps, you’re ready to run any Java application on your Windows 10 machine.
