On Minecraft Windows 10 Edition how do I update the game and install mods for the game?

Play roblox, its better

On the Windows Store there will be an update button, this is only for major updates, minor updates are installed automatically

As for the "mods" check here - http://www.minecraftforum.net/...10-edition

Note: It's a port of Minecraft PE so you won't be able to get actual mods, only minor things and uploading different worlds. If you want mods then you'll need the normal Java version
