This is for devices running Windows 10

Check Graphically

If you prefer to avoid the command line, you can use the About Java utility to find the installed Java version.

First, open the Start menu. Next, type in About Java in the Cortana search box in bottom left-hand corner. Now, click the first result in upper-left corner. Refer to below image:

Java 1
Accessing your About Java app

Next, you will see your current Java version listed in the first line. See below image:

Java 2
Your Jave Version and Update number

If you do not see About Java in the Start menu, search for Configure Java in the Cortana search box and click the result. Then click the About button to see your Java Version and Update number. See following image:

Java 3
Accessing the Java Control Panel About button

Note: If you do not see either the About Java or Configure Java tools, you likely do not have Java installed. You can download it here from Oracle’s official website. This may take several minutes; just be patient.

Check Using the Command Prompt

You can check your Java version from the command line, too.

First, open the Start menu. Next, type in Command Prompt in the Cortana search box in bottom left-hand corner. Now, click the Command Prompt app in upper-left corner. Refer to below image:

Java 4
Accessing the Command Prompt app

When the Command Prompt opens, type the following command at the prompt and press Enter.

java -version

Now, you will see your Java version and some numbers next to it. These numbers are your Java version and Update number. See below image:

Java 5
Your Java Version and Update number

If the Command Prompt says that Java is not recognized as an internal or external command, that’s probably because the system variables are not properly set; or perhaps because you do not have Java installed. Reinstall Java on your PC from the download it here link and this should fix the issue for you.

What is the Latest Java Version

To check this, open your browser and search for:

What is the Latest Version of Java for Windows 10

As of this writing , the latest version Update 281. I have Update 271, so I need to upgrade. You can download it here for the latest version from Oracle’s official website. This may take take several minutes; just be patient. You will be prompted to uninstall your older version, just click the uninstall button. When finished, close your Java dialog box. Now, go back to either method above on checking your Java version. See following image where I have updated to the latest version:

Java 6
Your updated Java Update number

Check Your Version of Windows

You are finished. You can do the above for Windows 8 or 7, but in the download, you have to choose the Windows operating system, either 32-bit or 64-bit, download link. To check this in Windows 10 , first, open the Settings app by pressing Windows+i or click Start, then the Settings icon in lower left-hand corner. Next, scroll down to:

System > About

On the right side, look for the System type entry. You will be showned two pieces of information; whether you are using a 32-bit or 64-bit operating system and whether you have a 64-bit capable processor. Refer to below image:

Java 7
Your operating system

For Windows 8, head to:

Control Panel > System

You can also hit Start and search for system. Look for the System type entry to see whether your operating system and processor are 32-bit or 64-bit.

For Windows 7, click on Start, right-click on Computer, and then choose Properties. On the System page, look for the System type entry to see whether your operating system is 32-bit or 64-bit.
