User info list can be accessed using following URLs. This is a hidden list there is no out of the box option to edit or delete the users from here. Initially I thought it requires custom solution to delete the users from here.
Simple view : ../_catalogs/users/simple.aspx
Detail view: ../_catalogs/users/detail.aspx
However if you delete the user from ‘People and Groups’ (All people view) using the following URL user info list also reflects it :-)
_layouts/people.aspx?MembershipGroupId=0&FilterField1=ContentType&FilterValue1=Person
