It can delete temporary files and system files, empty the Recycle Bin, and remove a variety of other items that you might no longer need. The option to cleanup updates helps reduce the size of the component store.

Step by steps:

1. Go to Disk CleanUp tool

2. Choose system driver (C) at Disk CleanUp : Drive Selection 

3. Choose all files to delete

4. Click OK to clean disk

5. Go to Disk CleanUp Tool again

6. Choose Clean up to system files

7. Click OK to clean disk.

Disk Cleanup tool helps your PC save about 5-6GB.

II. Task Scheduler

The StartComponentCleanup task was created in Windows 8 to regularly clean up components automatically when the system is not in use. This task is set to run automatically when triggered by the operating system. When run automatically, the task will wait at least 30 days after an updated component has been installed before uninstalling the previous versions of the component.

Step by step:
1. Go to Task Scheduler (Window + R > type "Taskschd.msc" OR Control Panel > Administrative Tool > Task Scheduler)
2. Expand Task Scheduler Library > Microsoft > Window > Servicing
3. Under Start Component Cleanup and click Run

Start Component Cleanup

III. Dism.exe

The /Cleanup-Image parameter of Dism.exe provides advanced users more options to further reduce the size of the WinSxS folder.

From an elevated command prompt, type the following:

Dism.exe /online /Cleanup-Image /StartComponentCleanup

IV. Hibernate Files
We will remove Hibernate file in system. It usually occupied about >= 1GB.

From an elevated command prompt, type the following:

powercfg -h  off

V. Turn Off Virtual Memory

If PC's physical memory enough large and you don't need Virtual Memory, you can turn off Virtual Memory so that save disk space.

Step by steps:

1. Go to Advantage System Setting.

Oracle Nashorn Engine is used interpreter JavaScript language. The scenario for Oracle Nashorn Engine as a command-line tool and embedded interpreter in Java Applications.
Note: Oracle Nashorn Engine be able to SE 9.

I. It's just javascript.
Example 1:

------------helloWorld.js------------
//start
var hello = function() {
      print("Hello Oracle Nashorn Engine");
};
helloworld();
//end
------------helloWorld.js------------

Evaluating it as simple as this:
$jjs helloWorld.js
Hello Oracle Nashorn Engine

Example 2:
------------helloWorld.js------------
//start
var sum = function (a, b) {
    return a + b;
};
print("Sum = " +  sum(3,4));
//end
------------helloWorld.js------------

Evaluating it as simple as this:
$jjs helloWorld.js
Sum = 7

II. Embedding Oracle Nashorn
Oracle Nashorn from a Java application to define javascript statements, call it as we write code in a javascript file. It helps when we want to load a javascript code to Oracle Nashorn and work on that.

Example:
package learning.javacore.oraclenashsorn.samples;

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class Sample1 {

private static final String NASHORN_ENGINE = "nashorn";

public static void main(String[] args) {

//declared ScriptEngineManager and ScriptEngine
ScriptEngineManager engineMrg = new ScriptEngineManager();
ScriptEngine engine = engineMrg.getEngineByName(NASHORN_ENGINE);

//declared a js codes.
String js = "var sum = function(a,b) { return a + b;};";

try {
engine.eval(js);
System.out.println(engine.eval("sum(3,4);"));
} catch (ScriptException e) {
}
}
}

We can do more with Oracle Nashorn. Please see details: http://www.oracle.com/technetwork/articles/java/jf14-nashorn-2126515.html
