I'm about to install the JDK, but I'm not sure which version I'm supposed to get Windowsx86 or Windowsx64. I'm running Windows OS but I don't know what the x86 and x64 means. Here is a link to the download:

x86 = 32bit, x64 = 64 bit.

x86 will work for you, x64 might perform better on a 64 bit OS

For 99% of use-cases, the x86 version is the right choice. install and use the x64 version only if you need the usage of a 64-bit browser or a stack that allow you to allocate more then 2 GB or ram per process.

The latter is actually a common and important need, for example with Eclipse and huge code bases. I strongly recommend the 64 bit Java SE SDK, without the browser plugin.

Also, you can install both. You can also point Eclipse to which JDK you want to use. In fact, this is a common annoying bug with Eclipse where you *HAVE* to point Eclipse to the JDK you want to use, as for some stupid reason, it uses your JRE instead.
