@Muhammad-Ahmad

what does that mean, you double-click on a bat file and it does not run, instead it gets opened
in notepad++? Or something different?
Which notepad++ and windows version do you use?

You must have associated *.bat files with another program or maybe even NPP?
See here how to reset it:

Or maybe this if above does not solve it:

You may have to restart Windows for this to take effect.
