Great information, JuneMouse. Thank you very much !
Hope Teerayoot will update his Olly Invisible plugin with this information.
This detecting way will return wrong information if the GlobalFlag of exe was set (by using Gflags.exe or by editting registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\TheEXE).
Creating a empty key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\debugcrap.exe] (no GlobalFlag value) in the registry will fool the detecting.
Best regards,
