Disabling the Java web plug-in RRS feed

  • Question

  • We've starting testing a method to disable the Java web plug-in in IE. We're using the registry settings from the KB at http://support.microsoft.com/kb/2751647. We've been able to push these settings from Group Policy successfully. We have however noticed that there are still a few plug-ins that are not affected by this change:

    Java(tm) Plug-In 2 SSV Helper

    Java(tm) Plug-In SSV Helper

    Are these Plug-Ins to be worried about and if so, does anyone have the registry settings to disable them?

  • Hi Sandy,

    they should not instantiated since your have 'disabled' the Java RT, however they will still be loaded into memory each time a window/tab is created...since they are of a type of addon called Browser Helper Objects (BHO's) (IsetSite is called on each tab/window creation). Their impact should be minimal, but they are probably best blocked with GPO as well.

    Generally I choose to uncheck the setting "Enable third-party browser extensions" on the Advanced tab of Internet Options (there is also a GPO setting for this).. that stops COM IE Addons (Toolbars and BHO's) from being loaded into the IE memory, but still allows scripted addons (Command bar buttons and menus, context menus) and ActiveX controls (Flash, MSOffice dll's).

    you can obtain their file name and CLSID values from the IE addons Manager (or by searching through the HKCR\CLSID node for their filenames)

    which you can use the CLSID values to add to your black lists using GPO.

     You can also use the Java control panel.... Start>Control Panel>Java 32>Java tab, 'View' button to disable their hooks (the java components however will still appear as 'enabled' in the IE Addons manager.... confusing?)
