We are all familiar that Java provides separate executables for Windows x86 and 64-bit operating systems. While it is possible to install and use an x86 executable on Windows 64-bit operating systems, it is impossible to install these executables silently using the system account due to a bug in Java. This has already been reported as a bug during last October and is yet to be fixed by Java.
As a result, to my knowledge, all the popular patch management solutions available in the market today will not be able to detect and patch the Java installations that use an x86 installable on a Windows 64-bit operating systems. You should either re-install Java with the executable for Windows 64-bit systems or have to manually update them using some scripts.
Desktop Central, in its recent update released yesterday, overcomes this Java bug to automatically detect and install patch updates to Windows x86 installable though you have installed it on a Windows 64-bit operating systems.
So, with Desktop Central in place, you would no longer require to worry about your Java updates irrespective of which installable you had used on you 64-bit systems.
Cool!
