The problem when you go to the control panel and disable Java updates when you close the window if you go back it is re-enabled, not sure why they would even have that if it doesn’t work.
I manage a lot of computers that reset themselves when the user logs of or the computer is rebooted, the java update popup is just an annoying waste of time for those users. For these I need to update when I say.
Also some of my equipment that I manage works best with old java and browser, I know there are work rounds but I have my own, I have a virtual desktop that I run what I need and it is okay since I only use it for certain task. Otherwise you should probably keep things up to date.
Using Explorer locate the java control panel (javacpl.exe)
The javacpl.exe file for 32-bit Windows Vista and higher is located at.
C:\Program Files\Java\jre6\bin\javacpl.exe, or
For Windows Vista x64, Windows 7 x64 or Windows 8 x64 you should instead look for:
C:\Program Files (x86)\Java\jre6\bin\javacpl.exe, or
