Customer would like to disable the next gen plug-in remotely for thousands of PCs and they say that this works when they do this via the Java Control Panel but fails when they try to do this through modification of a registry key. The problem is seen both with Windows XP as well as Windows Vista. It appears the customer has a legacy application which they need to also run on these systems using 5.0u22 and the application does not function properly when the next gen plug-in is enabled.
They specify to load their legacy application using family clsid:CAFEEFAC-0015-0000-FFFF-ABCDEFFEDCBA.
The customer has managed desktops, with user that have restricted policies that would
prevent them access to the Java Control Panel so customer must implement the setting change for them remotely during, nightly maintenance window.
Since the next gen plugin can be disabled in the Java Control Panel, there should also be a supported way to disable it via installation, registry or other method for multiple managed user desktop accounts.
Please see comments section and attachments for the test results from the customer.
