I'm trying to speed up a slow old laptop of mine. I couldn't help but notice that I have a ton of Java installed in my Add/Remove Programs section.

Here's what I've got:

J2SE Runtime Environment 5.0 Update 3 (117MB)
Java 2 Runtime Environment, SE v.1.4.2_10 (109MB)
Java ™ 6 Update 2 (111MB)
Java ™ 6 Update 3 (111MB)

That seems like 3 too many to me. Anyone have any good advice on what I can get rid of?

Thank you, guys,

Oh, I was kind of thinking about deleting all of them and letting Java prompt me on installing whatever is necessary. Is that a good plan?

Hello, telecomjohn.

Hope this answers your question:

Your Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system. Please follow these steps to remove older version Java components and update:
  • Download the latest version of Java Runtime Environment (JRE) Version 6 and save it to your desktop.
  • Scroll down to where it says "Java Runtime Environment (JRE)6 Update 5...allows end-users to run Java applications".
  • Click the "Download" button to the right.
  • Select your Platform: "Windows".
  • Select your Language: "English".
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • Click Continue and the page will refresh.
  • Click on the link to download Windows Offline Installation and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
  • Go to Start > Settings > Control Panel, double-click on Add/Remove Programs and remove all older versions of Java.
  • Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button.
  • Follow the onscreen instructions for the Java uninstaller.
  • Repeat as many times as necessary to remove each Java version.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on jre-6u5-windows-i586-p.exe
  • Follow the on screen instructions to install the latest Java version.
Good luck!

Hi telecomjohn,

I would remove all except Java 6 Update 3 (111MB). That one appears to be the most recent Java on yor box. Before you do anything wait to see some other responses to your question, there will be other posters that know far more about such things. I have removed all the lower (earlier) versions on my box and haven't had any problems. Seems like when there's an update, it doesn't uninstall the previous version. At least it didn't for me.

Hold off on doing anything until you get some more input, it doesn't hurt anything other than it's taking up space.

I would uninstal all the java listed, then using the link that Billy posted to instal the latest version. My java files are taking up 1GB of space.
