Java Runtime Environment (JRE) (64-Bit)

Oracle's Java Runtime Environment (JRE) for 64-bit Windows PCs contains the Java Virtual Machine, software libraries, components, and plug-ins that tons of programs, media, and Web sites need to display advanced multimedia content and animation. Version 7 Update 55 of Java's Standard Edition addresses 37 security vulnerabilities while reducing the frequency of security notifications in certain installations.

Pros:

Answers the 64-bit question: Running 32-bit Java on 64-bit Windows involves compromises, such as Update issues. This version of Java is designed specifically for 64-bit Windows.

Plug-ins: The Java plug-in is critical to many Web applications, while Java Web Start deploys standalone apps over networks.

JavaFX: JRE now includes Java FX version 2.2.55.

Cons:

Security: Some computer experts warn of vulnerabilities in Java that updates have failed to correct.

8 is enough? Java SE 8 is a major update that was released prior to version 7.55's release, though a major security update to version 8 has also been released. Confused? We don't blame you, but Java always bears watching, so check on your system's needs before upgrading.

Bottom Line:

If you're running 64-bit Windows, check your Java version and update it if necessary to JRE SE 7.55 for security and stability.
