Windows has grown larger and larger with each new version, what could once be installed with one DVD would now take about 4 DVDs to install from DVD disk. The latest Windows folder size on the insiders installed release (18262 build) is 16.9GB (4.49GB for the previous insiders release) in size plus there are many other folders and files added onto the root drive with the install as well.

Leaving out a lot made the Install quicker for the October release but meant the user would have to install more drivers and files, depending on the users needs later.
