Do you keep all the software that often comes with Windows (or is installed later) equally patched? Such as Adobe, Java, Macromedia etc?
Well, some of it. The trouble with Java is that it's so flaky that you tend to need to have a particular version installed for each application, as the applications are written to the particular bugs in a particular version of the JRE, so it's not realistic to simply run only the latest patched version.
