Remote desktop session host and metro notification.

Hello. 

I want to prevent using metro style notification on windows server 2016 with Remote desktop session host service.

For example if we start cmd and write : msg * "test" we will see 

but after Remote desktop session host service installation complete  it will be look like

My question... How can i disable using metro style notification in RDS?
Replacing msg.exe files doesn't help. 
Maybe some registry change or wmi solutions?

Thanks.
