Those are inherited from the parent folder, i. e., C:\.

$ icacls C:\\
c:\ S-1-15-3-65536-1888954469-739942743-1668119174-2468466756-4239452838-1296943325-355587736-700089176:(S,RD,X,RA)
    BUILTIN\Administrators:(OI)(CI)(F)
    NT AUTHORITY\SYSTEM:(OI)(CI)(F)
    BUILTIN\Users:(OI)(CI)(RX)
    NT AUTHORITY\Authenticated Users:(OI)(CI)(IO)(M)
    NT AUTHORITY\Authenticated Users:(AD)
    Mandatory Label\High Mandatory Level:(OI)(NP)(IO)(NW)

Funny enough, the C:\ default ACL on servers doesn't contain entries for
Authenticated Users.  The group Users is tasking its place.
