winapi - Win32 API for Deleting User Profile? -

one way of deleting user profile delete user profileslist registry key , delete user folder users directory.

on windows 8 though not seem sufficient. there seems data present in hklm related user too. 1 such example hklm\software\microsoft\windows\currentversion\appx\'usersid'.

hence i'm looking api (win32 sdk), delete filesystem , registry entries related user profile?
