I achieved the correct way of FILE ASSOCIATION using these cmd commands.
this is just an example:

REG ADD "HKEY_CLASSES_ROOT\Applications\notepad++.exe\shell\open\command" /v @ /t REG_SZ /d "\"C:\\Program Files\\Noteepad++\\notepad++.exe\" \"%1\"" /f
REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.txt" /v "Application" /t REG_SZ /d "notepad++.exe" /f
REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.txt\OpenWithList" /v "g" /t REG_SZ /d "notepad++.exe" /f

assoc .txt=MyCustomType
ftype MyCustomType="C:\Program Files\Noteepad++\notepad++.exe" "%1"

(it's better to put them in .bat file)
