I don't know is this right area but...

Why my Worms 3D game starts in windowed. I don´t have put any /WIN things or anything like that put still? Are there any like /FULLSCREEN or something like that.

I thing the right parameter is /FS (F ull S creen).

Check your shortcut command line if there is something weird what starts it to windowed mode. And of course you have installed DirectX 9.0c?

presing ALT GR + ENTER you go to fullscreen if you have the game windowed, and to windowed if it is running on fullscreen.
