High ROM Usage of Cubase Elements 10

Hi everybody,

I recently installed Cubase Elements 10 on my Thinkpad Yoga 14 with Windows 10.
I installed all additional software that is installed alongside Cubase by default.
Cubase Elements itself is about 17GB, but after I checked drive C of my PC, the free space dropped from 100GB to 50GB.
Does the additional software really take up that much space?
Where can I get an overview about that?
