The Windows UI could chose not show some partition types to prevent the user
from messing up the system.
A partition could contains diagnostics, an install image backup, or any number
of things that are not intended for the user to modify. So showing the user
these partition could lead to the user damaging the system. Believe it or not
all computer users have not read the UEFI spec and understand how GPT works :),
