Note that it is your responsibility to load the user's registry hive into the HKEY_USERS registry key with the LoadUserProfile function before calling CreateProcessAsUser.

This means that access to information in the HKEY_CURRENT_USER registry key may not produce results consistent with a normal interactive logon.
