Avoiding the welcome screen in Mathematica 12.1 at startup om windows

I would like to be able to avoid the welcome screen.
I have tried to uncheck to box Show at Startup and tried to change the frontend init.m file - and tried to use the option inspector.

You don’t say which version of Mathematica and which version of Windows are giving the trouble.

With Mathematica 12.1 under macOS Catalina (10.15.6), if I go to the Mathematica Preferences > Interface tab and in the “Show at startup” field select “New document” instead of “Welcome screen”, then indeed the next time I start Mathematica I get just a new notebook window and not any Welcome Screen.

Likewise, with Mathematica 12.1 under Windows 10 (running as a virtual machine inside Parallels Desktop for Mac version 16, again under macOS Catalina), if I go to the Mathematica Edit > Preferences > Interface tab in the “Show at startup” field select “New document” instead of “Welcome screen”, then indeed the next time I start Mathematica I get just a new notebook window and not any Welcome Screen.

I work with 12.1.1 on MacOS Catalina - 10.15.6
And yes it works.

Thanks
