Windows Registry, how to add your Native-Program for boot-exectuing?

I have done my Native program for Windows.

( which, I've compiled with #pragma comment(linker, "/SUBSYSTEM:NATIVE")).

I want to add my program to auto-executing list, how can I do it?

My exact questions are:

1). How can I do it in Windows Registry ( I have googled about BootExecute/SetupExecute table, but Setup is empty and BootExecute has only: autocheck autochk * ). So I was confused of empty tables ( cause , if it's empty, where are another auto-exec programs in Windows, which ntdll.dll does load ? )

2). Does it matter what is the version of the executable program: for 32/64 bits system?

I have put it in %windir%\system32, but there is also %windir%\WOW64 folder.

Should I highlight this detail in Registry or Windows loads each driver from both folders and just simply highliht them as *32 or 64 bits program in taskmgr?

3). Are there any other ways to do that?

Thanks,

Best Regards!
