JAVA Update Check Frequency - Once a Month by Default - How to Change it, and Why You Should

JAVA Update Check Frequency - Once a Month by Default

How to Change it, and Why you Should

I just checked the default JAVA Update Check Frequency. Turns out it is EVERY MONTH. I figured this needs an adjustment, given what we now know! There should be several more 0-day updates necessary to protect yourself from immediate exploitation by simply visiting the wrong site! To change this, you need to find the "Java (32-bit)" shortcut. Be sure to 'Run as Admin', else it will - without error - not actually apply your changes!

The actual executable backing the shortcut is in %PROGRAMFILESDIR%\Java\bin\javacpl.exe (Java Control Panel). That's "Program Files" for 32-bit Windows installations, or "Program Files (x86)" for 64-bit Windows installations.



Note that this may not *always* matter, as the browser you use may have its own internal implementation of Java, and/or enforce Java updates more regularly. However, I figure, why take the chance?
