I like to be sure that everything will work just by copying the contents of the Java folder and setting the environment variables. I usually run the installer in a virtual machine, zip the \java folder contents, go back to a snapshot of the virtual machine, and then unzip the compressed file. I couldn't find a place where the latest JRE / JDK is available as a zip file... http://java.sun.com/javase/downloads/index.jsp http://download.java.net/jdk6/ Alternately, is it safe to assume that exe installer from sun just will just unzip the whole thing, without messing around with the registry, environment variables, etc...? <h3>Related: Installing Java manually on Windows? </h3> -- After all this time I found this site that seems to be exactly what I was looking for (2018-05-22)

JDK is not available as a portable ZIP file, unfortunately. However, you can follow these steps: <ul> <li>Create working JDK directory (<code>C:\JDK</code> in this case)</li> <li> Download latest version of JDK from Oracle (for example <code>jdk-7u7-windows-x64.exe</code>)</li> <li> Download and install 7-Zip (or download 7-Zip portable version if you are not administrator)</li> <li>With 7-Zip extract all the files from <code>jdk-XuXX-windows-x64.exe</code> into the directory <code>C:\JDK</code> </li> <li>Execute the following commands in <code>cmd.exe</code>: <ul> <li><code>cd C:\JDK\.rsrc\1033\JAVA_CAB10</code></li> <li><code>extrac32 111</code></li> </ul> </li> <li>Unpack <code>C:\JDK\.rsrc\1033\JAVA_CAB10\tools.zip</code> with 7-zip</li> <li>Execute the following commands in <code>cmd.exe</code>: <ul> <li><code>cd C:\JDK\.rsrc\1033\JAVA_CAB10\tools\</code></li> <li> <code>for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar"</code> (this will convert all <code>.pack</code> files into <code>.jar</code> files)</li> </ul> </li> <li>Copy all contents of <code>C:\JDK\.rsrc\1033\JAVA_CAB10\tools</code> where you want your JDK to be</li> <li>Setup <code>JAVA_HOME</code> and <code>PATH</code> manually to point to your JDK dir and its BIN subdirectory.</li> </ul>

<ul> <li>Create destination folder where you can RWX (e.g. <code>C:\jdk8</code>)</li> <li>Download jdk exe from Oracle (e.g. <code>jdk-8u72-windows-x64.exe</code>)</li> <li>Unzip the <code>tools.zip</code> found inside it into the destination folder</li> <li>In <code>cmd.exe</code>, run: <ul> <li><code>cd C:\jdk8</code></li> <li><code>for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar"</code></li> </ul> </li> </ul> This solution works for JDK 8 too, without Admin rights.

JDK is not available as a portable ZIP file, unfortunately. However, you can follow these steps:

Create working JDK directory (C:\JDK in this case)
Download latest version of JDK from Oracle (for example jdk-7u7-windows-x64.exe)
Download and install 7-Zip (or download 7-Zip portable version if you are not administrator)
With 7-Zip extract all the files from jdk-XuXX-windows-x64.exe into the directory C:\JDK
Execute the following commands in cmd.exe:
- cd C:\JDK\.rsrc\1033\JAVA_CAB10
- extrac32 111
Unpack C:\JDK\.rsrc\1033\JAVA_CAB10\tools.zip with 7-zip
Execute the following commands in cmd.exe:
- cd C:\JDK\.rsrc\1033\JAVA_CAB10\tools\
- for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" (this will convert all .pack files into .jar files)
Copy all contents of C:\JDK\.rsrc\1033\JAVA_CAB10\tools where you want your JDK to be
Setup JAVA_HOME and PATH manually to point to your JDK dir and its BIN subdirectory.

Create destination folder where you can RWX (e.g. C:\jdk8)
Download jdk exe from Oracle (e.g. jdk-8u72-windows-x64.exe)
Unzip the tools.zip found inside it into the destination folder
In cmd.exe, run:
- cd C:\jdk8
- for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar"

This solution works for JDK 8 too, without Admin rights.
