Mojang-created Minecraft has required that you installed Java’s run-anywhere code base — a problem considering that the latter tends to introduce security exploits and adware.
However, the construction game will be considerably safer thanks to a low-key update. Minecraft’s Windows edition (and OS X later this year) now installs a standalone version of Java that’s only used while you’re playing. You can also scrub the full version of Java without losing access to your blocky masterpieces.
If you haven’t been keeping up with your software updates, the game may run smoother at the same time. It’s not exactly an urgent upgrade, but it’s definitely a satisfying one if you only bother with Java to live in Mojang’s blocky 8-bit universe.
