How to disable the Java web plug-in in Internet Explorer

INTRODUCTION

Java is a unique form of extensibility because it can be invoked in the following two ways:

• By using an
  applet element

• By using an
  object element that has a CLSID of a Java virtual machine (JVM)

These two invocation methods are subject to different security controls. This Knowledge Base Article contains an easy fix solution  to disable the Java web plug-in from being loaded through these controls. The easy fix solution will also disable the Java Network Launching Protocol (JNLP) handler.
