just as this link says : http://untidy.net/blog/2009/11/03/replacing-notepad-with-pn-via-image-file-execution-options/

I wanna replace Notepad.exe to Notepad2.exe using "Image File Execution Options" function by run this command

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "\"c:\windows\Notepad2.exe\" /z" /f

but, when I run notepad, it open file c:\windows\notepad.exe in notepad2.exe as a text file by default. Is there a way to avoid that?

I know using this tech Notepad.exe will as the first param passed to Notepad2.exe. but I don't know how to avoid this :(
