There is no easy way to disable java from inside IE. maybe the best choice is to disable it from the java control panel.

If you don’t afraid of Regedit and delete system files you can create a .reg file with the following and inject it into your registry:

[HKEY_CLASSES_ROOT\JNLPFile]
@=”JNLP File”
“EditFlags”=hex:00,00,00,00

Further disabling can be done by removing the file “jp2iexp.dll“; commonly located at:

  • C:\Program Files\Java\jdk{version}\jre\bin
  • C:\Program Files\Java\jre7\bin
  • C:\Program Files\Oracle\JavaFX {version} Runtime\bin

Locate and delete any instances of the “npjpi[version].dll” file, where [version] is a string representing the version of Java installed (e.g. npjpi170_06.dll). That file is commonly located:

  • C:\Program Files\Java\jdk[version]\jre\bin
  • C:\Program Files\Java\jre7\bin
  • C:\Program Files\Oracle\JavaFX [version] Runtime\bin
