Our windows installers have a zipper.exe file that we build that unzips the JRE into the target directory. In JDK7, we now have a nice installer.dll that is built using a project solution. We should add this zipper code to the installer.dll, so we can remove the extra executable. This will simplify the MSI, make development easier, and allow us to do better things going forward as a whole.

Our windows installers have too many levels of execution, making it hard to debug and hard to write unit tests. At some point in JDK7, we want to only make one call from the msi to the installer.dll, and it should do all of the unzipping, unpacking, and registering. This is one step in that direction.
