Sometimes you may not want to update the whole system and just update Blender, the final version will have a Blender updater!. This is how to do it until then. 

Using the update manager

You will find the update manager under system in the menu, you can use it to update your whole system or just parts of it. So to update Blender, if its showing in the update manager that means there is a new version available(which there is almost every day) Just check the box next to Blender and uncheck any updates you don't want then click Install updates.
