Java: A Resource Hog?

Something that still causes a lot of trouble on many Windows x64 machines is Java. Java is needed for all those cool web 2.0 applications and for games like Minecraft, but it’s also a resource hog and is often causing a very high CPU load, therefore many people deactive it completely. Nonetheless, it’s an important download.

What is Java 64-bit needed for?

Answer: For a 64-bit browser.

Yes, you can run Java 32-bit on your x64 Windows 7 system, but if you download and install Java 64-bit, you can also run any 64-bit browser. Firefox for example offers a 64-bit browser for Windows 7 x64. By default, Windows 7 includes a x32 and x64 edition of the Internet Explorer 8.

IE9 64-bit location:

Where can I find the different 64-bit browsers?

  • IE9 32-bit: C:/Program Files (x86)/Internet Explorer/
  • IE9 64-bit: C:/Program Files/Internet Explorer/

Firefox 64-bit download:

Usage solely depends on your purposes. 64-bit browsers are not needed for the average consumer and are considered unstable most of the time. A browse called Waterfox, based on Firefox, claims it is the most reliable 64-bit browser. If you have a real need to look into this, I suggest you try Waterfox first.

JDK: Required For Some Java Apps (Rare)

The JDK includes a 64-bit plugin for Windows. The JRE does not include this plugin, so you will have to download this large file in some cases (VERY rarely). You can download it here:
