Not the newest Java version (Minecraft Installed Launcher)

This is not actually on the Project "Minecraft Launcher", instead it belongs to the "Minecraft Windows installer".

As far as I know it is supposed to keep Java updated automatically.
On my PC I have Java 8 64 bit Update 51 installed.
Using the Minecraft Windows installer launcher, Java version 8 64 bit update 25 is used instead.
This might be working as intended, but it still isn't the best solution.
