I got sick of Java updates on Windows trying to trick me into installing McAfee or the Ask toolbar, so I went searching for a solution. I found a different build of Java from Oracle that solves the issue.
Go to this page: http://www.oracle.com/technetwork/java/javase/downloads/index.html
Click on the top Download button in the JRE column.
Accept the License Agreement, then choice to download Windows x86 Offline.
This can then be installed and it will not try to get you to install crapware. It can even be installed from the command line without requiring any further user interaction (see: http://java.com/en/download/help/silent_install.xml).
