SQL Server 2016 Management studio regular update

Question

Since ssms is now separated from the SQL Server installation, what is the easiest way to to keep it up to date withought downloading the entire setup again? I couldn't find a check for update button anywhere.

Answer 1

Update 03/01/2018:
You don't need to install the whole package.. you can click on below highlighted link which is around 300MB in size ..

As you can see in below screenshot, you are provided with an option to install latest version(17.5) or just upgrade from 17.X version to latest version..

Old :

You can't download SSMS with out installing whole setup

1.If you are on windows10 latest version.,you will receive a popup which shows an update available whenever you login to SSMS

2.you also can check by going to tools-->updates in SSMS and you get below screen and clicking on update will lead you to installer page

3.You also can download installer from this page(which will always install latest version)
