I have no idea either because I don't know programming but this website: What is Java and can I do without it? Says: To summarize: if you don't update JAVA and don't update your apps, then you might be O.K. for your system not dying (of course, you might be leaving yourself open for a vulnerability or two). If you get new software, it might come with a version-specific JAVA requirement so watch out for that. As for uninstalling it altogether, that could be problematic for various applications but you should find that out pretty quickly ("Oh, the backup software can't load...."). In that case, you can always reinstall. If you look at your task manager (Windows) at the processes and you see JAVA.EXE using the processor, that could be a sign you need JAVA. JAVASCRIPT is a scripting language based on JAVA that usually runs websites. Many suggest disabling scripting in your browser as a security means, but, if one of the websites you frequent requires that, you would need to turn it on again. You system may not become crippled for any of this but some of your applications might if JAVA is removed. Also, if you have trouble uninstalling JAVA, it could mean that one of your startup applications uses JAVA. Again, its an "application thing". If anyone sees something I said incorrectly, please let me know. I'd appreciate it.
