windows 10 - pin default microsoft programs to start menu

I'm sorry to ask such a silly questions here, but you probably can reply more faster than Microsoft :) So, I'd like to pin the default "Calendar" app to the start menu on my new windows 10, but I can't. I can pin everything which is not default program like Microsoft Office, Google Chrome, etc... But I can't pin a lot of for example Calendar, Calculator, Mail and etc...

Am I silly or isn't it possible?

Thanks!

p.s: sorry for my grammar, but I'm not a native-speaker.

Solution

you should be able right click on any application and choose to pin to start menu.
