is there a document which let me know what are the HKLM registry hives are accessible from Native C++ program. I am writing a C program which will run using BootExecute and will access read / write reg entries. I could do it successfully under \Registry\Machine\System\ControlSet001\Services however if I am trying to access \Registry\Machine\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\RunOnce or \Registry\Machine\Software\Microsoft\Windows\CurrentVersion\RunOnce
it fails. Is there a document or information which helps me to let know what all registry are accessible during OS boot, will be helpful.
